How Security Design Patterns Are Important Tools For...
A security pattern describes a specific security problem which arises in a given context and provides
a sound, time–tested solution for the problem (Schumacher, Fernandez–Buglioni, Hybertson,
Buschmann, & Sommerlad, 2006). Security design patterns are important tools for secure software
engineering. In this section, we give a review of the literature on security design patterns. The
survey covers patterns published at the PLoP (Pattern Languages of Programs) conferences, the hub
of the patterns research community, pattern books, scientific databases as IEEE Xplore, the ACM
Digital Library, SpringerLink, etc., and papers from prominent indexing systems. We focus on three
categories of literary works related to this domain:
i. Patterns and pattern catalogs ii. Pattern classification iii. Survey papers
3.2.1 Patterns and Pattern catalogs
In their seminal paper on security patterns, Yoder and Barcalow (1997) present a case for the
importance of security in applications designed for the corporate environment. They present a
collection of 7 patterns which can be applied during system design and implemented late in the
development. These patterns are : SINGLE ACCESS POINT which helps solve back door access to
sensitive data by limiting application entry to one single entry point. The SECURE ACCESS
LAYER pattern enables secure communication between an application and external systems. The
CHECK POINT pattern provides for user validations in order to prevent security breaches.

An independent quality assurance team defines "test cases" to evaluate whether the product fully or
partially satisfies the requirements outlined in the first step. Three types of testing typically take
place: unit testing of individual code modules; system testing of the integrated product; and
acceptance testing, formally conducted by or on behalf of the customer. Defects, if found, are logged
and feedback provided to the implementation team to enable correction. This is also the stage at
which product documentation, such as a user manual, is prepared, reviewed and published.
5. Maintenance
This step occurs after installation, and involves making modifications to the system or an individual
component to alter attributes or improve performance. These modifications arise either due to
change requests initiated by the customer, or defects uncovered during live use of the system.
Actually, every change made to the product during the maintenance cycle is recorded and a new
product release which is called a "maintenance release" and exhibiting an updated revision number
that is performed to enable the customer to gain the benefit of the

The Atomic Energy Of Canada Limited
Brief History (MICHAEL TABB)
Merriam–Webster has defined reliability as: "the extent to which an experiment, test, or measuring
procedure yields the same results on repeated trials".[1] As technology advances, so does the use of
computing and software in health services. With the onset of cancer, Atomic Energy of Canada
Limited (AECL) created a medical linear accelerator known as the Therac–25. The machines
responsibility is to accelerate and increase the energy of electrically charge atomic particles by the
introduction of an electric field focused by magnets. These accelerators are used to treat cancer
patients with radiation to remove malignant cancerous cells and tissue. The use of the machines
caused radiation overdoses between 1985 and 1987 causing loss of life and limb for patients in six
accidents.[2]
These six accidents began 3 June 1985 with a sixty–one year old woman receiving her twelfth
treatment at Kennestone Regional Oncology Center in Marietta, Georgia. She had her breast
removed and lost the use of a shoulder and arm after feeling a "tremendous rush of heat and red–hot
sensation", while receiving follow–up treatment for a malignant tumor removed from her breast in
that facility (Porrelo, A.). The second accident occurred at the Ontario Cancer Foundation clinic in
Canada on 26 July 1985 where a forty–year–old patient was in receipt of her twenty–fourth Therac–
25 treatment. During the treatment, the machine issued an "H–tilt" error message. This prompted the

Description And Description Of A Design Pattern
A design pattern must be represented in a structured manner so that it can be understood clearly and
unambiguously. A good description enables the reader to grasp the essence of the pattern. It is
expressed formally in terms of a pattern template. Several pattern template formats have been
designed and used by researchers. The template used in this research work is based on the POSA
book. Its elements and the description of each element are shown in Table 2.1. Element Meaning
Name The pattern name. Context Description of the situation giving rise to the problem. Problem
Description of the recurring problem arising in the context. Forces Description of why the problem
is difficult to solve. Solution Description of the proven solution to the problem. Also Known As
Aliases – other names for the pattern. Example A real world example which brings out the need for
the pattern. Structure A specification of the structural aspects of the pattern. Dynamics Description
of the run–time behavior of the pattern. Implementation Guidelines for implementing the pattern.

Path Analysis Paper
Main analyses involved running each of three models through AMOS SEM software separately,
using path analysis techniques to assess direct and indirect effects, among the present observed
variables (Arbuckle, 2013). Path analysis, which is based on multiple regressions, examines the
relationship between exogenous (i.e., variable not causes by another variable, but effects one or
more variables in model) and endogenous variables (i.e., a variable that is caused or effected by one
or more variables in a model; Iacobucci, 2010). Path models examine the total effects, as well as the
direct and indirect of effects of variables in a single model, simultaneously (Peterson et al., 2014).
Structural equation modeling path analysis techniques are superior to standard regression analyses in
that they: 1) provide more accurate estimates of the effects of hypothesized variables; 2) estimate all
effects simultaneously; 3) allow for greater accuracy of parameter estimates when examining
competing models; and 4) allow the researcher to compare effects of multiple mediators (Zhao,
Lynch, & Chen, 2010).
Mediation Testing. Data were fit to the path model using AMOS SEM software. For Model 1(see
Figure 3) and Model 2 (see Figure 4), ethnic identity was examined as a mediating variable between
community participation– neighborhood sense of community and psychological empowerment
(Model 1) and 30–day substance use (Model 2). For Model 3 (see Figure 5), psychological
empowerment was examined

That is why it is important to involve the user when determining the requirements for the system.
The more closely a software product meets its specified requirements, and those requirements meet
the wants and needs of its customers, the higher its quality. The more defects there are in software,
the more time engineers spend fixing them, taking time from other important project tasks. Also, the
more defects that exist, the more likely that software changes necessitated by fixing these
defectswill themselves result in more defects. For all these reasons and more, quality is one of the
most important attributes in software and a key contributor to its success.
– The later in the development cycle they are discovered the more they cost to repair.
– According to Boehm [2] and others, the cost of defect repair after software is released to
customers can be
100 times greater as compared to fixing the same defect early in the development cycle.
– Verification: ''The process of evaluating a system or component to determine whether the products
of a given development phase satisfy the conditions imposed at the start of that phase.''
For example, is the software design sufficient to implement the previously specified requirements?
Does the code fully and correctly implement the design?

This is particularly evident with connected speech recognizers, which are nonetheless more
attractive for many applica¬tions, as they allow more natural spoken input.
We use speech recognizers to transform speech to text using grammar below.
Grammar:
public = ()| (there) | (move) (that) | (delete)| (this); = create | put; = [a] (yellow | red | blue | black |
green); = square | triangle | circle | rectangle;
The equivalence of the grammar using graphs: Figure 9 Graphs describe the grammar
Commands:
"Create or put": "Create a blue square." Effect of complete utterance is a "call" to the create routine
which needs object to be created (with attributes) as well as x, y pointing input from mouse or eye
Tribe.
"Move": "Move that there" effect a displacement from old position the new one pointing by mouse
or eye Tribe too. "Delete": "Delete that" this command used to deleting an object by pointing input.
"There or this": those command help to extract the pointing input from mouse.
The grammars above help us to extract only what we want as speech and ignore the rest. After using
this grammar we extract sentence or words like:
Create a yellow square.
Put a red circle.
There
Delete
This
Move that
b) Keyboard and Mouse (input): After the speech the user can use the mouse with a simple left click,
to point the position where he wants to create or select or

VeriType is developing software that will improve the billing process for physicians. The software is
developed to help make the billing process easier, more accurate, efficient, and compliant with the
Health Care Financing Administration (HCFA). HCFA monitors billing practices compliance with
government regulations. Fines imposed for noncompliance with HCFA guidelines can reach up to
$10,000 per claim. This along with other inefficiencies in the billing process can cost physicians a
lot of money. (Moot Corp, 2013) VeriType's software is designed to improve the billing process and

Job fairs that focus on medical professions, technical support, or development are great
opportunities for the HRM or a representative to be present and expose potential candidates to
VeriType's career opportunities. Training and development will play a huge role in the success of
VeriType. HRM is critical in developing the proper training and development of most companies.
The training of both the software development team and the technical support staff will be important
in the success of VeriType. Employees must be trained in HCFA guidelines so that they can ensure
the software is operating effectively. Employees must be competently trained in how to educate and
help customers. The steps an effective training and development plan include determining specific
needs, establishing specific objectives, selecting methods/delivery systems, implementing programs,
and finally evaluation. (Mondy, 2014) VeriType wants to develop and launch their software geared
to help physicians alleviate billing problems and ultimately avoid costly HCFA violations. This
requires knowledgeable and experienced software developers and skilled technical support staff.
The HRM should discuss this training process with Jennifer Brunner, CEO, she has experience in
database development and contacts in the software development community. Jennifer should be able
to provide valuable resources to the HRM. She may also be capable of training employees. Once the

Software Engineering : Design Rules For All Components
In software engineering, requirements from user met with available components, then following
activities needs to be performed
1) Component Qualification: System requirements and architecture define the components that will
be required. Reusable components (whether COTS or in house) are normally identified by the
characteristics of their interfaces. That is, "the services that are provided, and the means by which
consumers access these services" are described as part of the component interface. But the interface
does not provide a complete picture of the degree to which the component will fit the architecture
and requirements. The software engineer must use a process of discovery and analysis to qualify
each component's fit. 2) Component Adaptation: we noted that software architecture represents
design patterns that are composed of components (units of functionality), connections, and
coordination. In essence the architecture defines the design rules for all components, identifying
modes of connection and coordination. In some cases, existing reusable components may be
mismatched to the architecture's design rules. These components must be adapted to meet the needs
of the architecture or discarded and replaced by other, more suitable components.
3) Component Composition: Architectural style again plays a key role in the way in which software
components are integrated to form a working system. By identifying connection and coordination
mechanisms (e.g., run–time properties

The Systems Development Life Cycle
Introduction:
"The systems development life cycle (SDLC) is the process of determining how an information
system (IS) can support business needs, designing the system, building it, and delivering it to users"
[1]. There are several approaches (models) to the SDLC but purpose of the each approach is the
same. Each and every process comprises of phases: Planning phase, Analysis phase, Design phase,
Implementation phase, and Maintenance phase. The Planning phase is phase related to the planning
of the system such as initial system request, feasibility analysis and project plan; Analysis phase is
the phase which is related to the analysis of the system, in this phase analysis such as requirement
definition, use cases, mental/logical process ... Show more content on Helpwriting.net ...
It also identifies the important risks associated with the project that must be managed if the project
is approved [1].
Example:
Now to go into further details of the feasibility, we have to define the types of feasibility. There are
three types of feasibility
Technical Feasibility– It is the type of feasibility which deals with the technical specifications of the
system and verifies the project feasibility within the limits of current technology? Does the
technology exist at all? How complex is the system? These are the various aspects which are dealt in
the technical feasibility of the system [1].
Economic Feasibility– It is the type of feasibility which deals with money related issues in the
company. This is also known as cost–benefit analysis. This attempts to answer the question "Should
we build the system?" Economic feasibility is determined by identifying costs and benefits
associated with the system, assigning values to them, calculating future cash flows, and measuring
the financial worthiness of the project. As a result of this analysis, the financial opportunities and
risks of the project can be understood. These are the aspect which are dealt in economic feasibility
[1].
Organizational Feasibility– It is the type of feasibility which deals with "how well the system
ultimately will be accepted by its users" [1], how is the overall market for the system, is there any
legal concern about the system? [1]. The various organizational factors that can

Training For Building Secure Software Security Activities
The BSIMM states that intelligence practices result in collections of knowledge to use to carry out
software security activities throughout your organization (2015). The collection of security
knowledge included in the intelligence domain are policy, standards, design and attack patterns in
reference to a secure architecture and secure development framework within the SSF (McGraw,
2006). This domain provides the essential resources to equip the staff with the necessary training for
development and delivery. McGraw (2006) traced that the topics included are security knowledge
and assurance activities with retrofitting of the existing courseware to software security concepts.
Moreover, the SAS stated that the secure developments standards are met in the proper deployment
of the intelligence domain. According to the SAS SSF, developers work with the standards and
guidelines that provide the foundation for building secure software (SAS, 2015). The three practices
of intelligence domain are attack models, security features, and standards and requirements. First,
Attack models capture information used to think like an attacker: threat modeling, abuse case
development and refinement, data classification, and technology–specific attack patterns (McGraw,
2004). Second, Security features and design practice is charged with creating usable security
patterns for major security controls meeting the standards defined in the next practice, building
middleware frameworks for those

Analysis and Design Phases Description
Software Engineering is the whole process of developing a software product from beginning to end
using an accepted methodology. One of the common and oldest methods is the Waterfall model
which sets a linear sequence of progression from Requirements gathering and analysis, design,
implementation, testing to maintenance (Philip L, Matthew, &Nick, 2002).
Fig (1) the waterfall model of software development
The five common stages include
1. Analysis
At this stage the system requirements are collected and defined. Every existing systems can also be
evaluated and each inadequacy can be highlighted.
2. Design
A design specification is taken from requirements analysis, which plans are prepared related to
physical construction, hardware, operating systems, programming, communications and safety
issues.
3. Build
Using the design specification, the system is developed and elements built. Additionally, the system
will also be tested and user training will happen.
4. Implement

The system is installed and implemented. That is, through any a gradual phased process or through a
more cost

Extreme Programming Up Front Design Methodologies Essay
Extreme Programming (XP) has spent the past decades under perpetual scrutiny by software
developers fixated on up front design methodologies. The idea behind this is simple: if you want to
make sure something is well built, you must design it well first, then put it together using reliable
tools. For objects such as houses, cars, or tables, of which the design evolves gradually throughout
decades, the methods of up front design suffice. Computer programs, on the other hand, are products
often made for an industry that evolves at higher rates than any other. For this type of environment,
more dynamic methods are required, which is why XP suits as a viable candidate. How design is
altered from the traditional up front design method will be ... Show more content on Helpwriting.net

"reveals all the intentions", on the other hand, makes sense under the following train of thought: if
something is simple, it is easy to understand, and therefore all or most intentions are clear to the
observer. "does not have duplicated code" seems to make things easy to understand, but may not
necessarily simplify a program. Finally, "has the fewest number of classes or methods" seems to be
the most pertinent to the concept of simplicity. If a system consists of less functional elements than
another one but holds the same product, it could be considered simpler. Following this definition, a
system that contains the least amount of functional elements than any other, but holds the same
product, could be considered simplest. Other than a few definitions of simplicity, Fowler mentions
YAGNI, an acronym he claims is one of the "...greatest rallying cries in XP..." (Fowler). It stands for
"You Aren't Going to Need it" (Fowler). The idea is summed up by Fowler as a method to only
program what is currently needed for the project. This is supposed to allow easy changes to be made
when needed. An example: consider the scenario where a calculator is being programmed. Its design
incorporates 'addition' and 'multiplication'. Whilst implementing 'addition', it may seem logical to
add some of the 'multiplication' features to reduce the amount of future work. Suddenly the client
decides to replace 'multiplication' with 'division'. 'multiplication' now has to be removed or

Advantage And Disadvantage Of Ssdm
SSADM is an analysis and design methodology that follows a structural tactic for Implementation of
a system. In the beginning of 80th of the past century this method was developed for government of
Great Britain. In 1993 it was accepted as the national standard of Great Britain and as a reason the
SSADM usage is expedient for those who work with governmental organizations and this method is
a standard for these organizations.
Unlike the conventional approach SSADM is DATA driven and data modeling begins very early in
the development of Information system. . SSADM may also represent the document–led approach to
system design, and can be contrasts with Rapid Application Development Method such as Dynamic

Advantage of SSADM
Timelines:–On the whole SSADM allows for the chance to plan, direct and control a project well.
Usability: – emphasizes the analysis of user requirements. Additionally system model will be
developed and a helpful analysis will be carried out. It has got an ability to change in business
environment. Documentation of project development is recorded critically and this helps to address
the planning of the project to the actual requirement of the business.
Effective use of skill:– It can be easily taught to employees because it does not need a special
expertise.
Better quality:–It helps to cut mistakes of information system by telling a certain quality level in the
beginning and often reviewing the new system.
SSADM increases the overall productivity of the project and the organization by meeting business
needs, ensures better quality, improving on the dot delivery and engaging human resources

Gang Of Four Design Pattern Analysis
Gang of Four Design Patterns
This section gives a high–level description of the twenty–three design patterns described by the
Gang of Four. Each pattern description includes a link to a more detailed article describing the
design pattern and including a UML diagram, template source code and a real–world example
programmed using C#.
Creational Patterns
The first type of design pattern is the creational pattern. Creational patterns provide ways to
instantiate single objects or groups of related objects. There are five such patterns:
Abstract Factory. The abstract factory pattern is used to provide a client with a set of related or
dependant objects. The "family" of objects created by the factory are determined at run–time.
Builder. The builder pattern is used to create complex objects with constituent ... Show more content

The singleton pattern ensures that only one object of a particular class is ever created. All further
references to objects of the singleton class refer to the same underlying instance.
Structural Patterns
The second type of design pattern is the structural pattern. Structural patterns provide a manner to
define relationships between classes or objects.
Adapter. The adapter pattern is used to provide a link between two otherwise incompatible types by
wrapping the "adaptee" with a class that supports the interface required by the client.
Bridge. The bridge pattern is used to separate the abstract elements of a class from the
implementation details, providing the means to replace the implementation details without
modifying the abstraction.
Composite. The composite pattern is used to create hierarchical, recursive tree structures of related
objects where any element of the structure may be accessed and utilised in a standard manner.
Decorator. The decorator pattern is used to extend or alter the functionality of objects at run–time by
wrapping them in an object of a decorator class. This provides a flexible alternative to using
inheritance to modify

Technology Architecture Designed For Safety Related Systems
Author
Weihang Wu and Tim Kelly
Article Summary:
The article highlights an approach to software architecture designed for safety–related systems. It
talks about the importance of safety strategy in software architecture design. It addresses three
issues to improve the architecture designs for safety–related systems.
Design Techniques: There have been a lot of advancements in software design techniques. There are
many design techniques available but choosing the right for the system is absolute critical. Therefore
this approach fails in demonstrating which design technique needs to be chosen to increase the
protection against failures.
Architectural Patterns: Architectural Patterns or styles consist of components and connectors, which
connect these components based on a set of restrictions, which describe how the components of a
particular kind can be connected. There are a lot of architectural patterns available, which display
different safety patterns. It is recommended to understand the basic design patterns and for creating
a good architecture.
Safety Analysis: There are a number of safety analysis techniques for software design, but there has
been very little analysis on architectural level to support software architecture design. Therefore a
safety analysis approach is needed for software with hardware to characterize the architectural
elements at various architectural levels.
The article talks about strategic tactic to address the above three issues which

The term cohesion is used to indicate the degree to which a class has a single, well–focused purpose.
Cohesion can be applied to classes and methods which should display a high degree of cohesion.
1.1 Cohesion of methods
From our assignment I took the Example of a cohesive method in Game class. public void play() {
Room r3 = house.getRandomRoom(); //v1 was getRoom(10) currentPlayer.setRoom(r3); //v1 was

// Enter the main command loop. Here we repeatedly read commands and // execute them until the
game is over. boolean finished = false; while (! finished) { Command command =
parser.getCommand(); finished = processCommand(command); } System.out.println("Thank you
for playing. Good bye."); }
/** * Print out the opening message for the player. */ private void printWelcome() {
System.out.println(); System.out.println("Welcome to ClueDark " + VERSION + ", the murder

Medisys Case
MediSys Corp. :The Intense care Product Development Team
(Anne Donnellon Joshuad.Margolis)
It was just six months away from MediSys 's planned August 2009 launch of IntensCare, their new
remote monitoring system for use in hospitals ' intensive care units. The company was investing
$20.5 million in the new system, which represented the most ambitious project in the company 's
10–year history.
Valerie Merz, marketing manager for IntensCare, was feeling enormous pressure as she reviewed
the agenda for the upcoming meeting of the product development team. Once again there was no
scheduled time to resolve the debate over the modular design that she knew was critical to
successful adoption and long–term success in the market. Without ... Show more content on

2. Once the leadership agreed on a new idea , Marketing developed product descriptions from
customer needs & responses to new Medisys concepts, & then passed these on to product
Engineering & Software Design
3. Engineering & Software design developed them into product specifications, & passed those on to
the regulatory group who researched and, where necessary, conducted clinical trials to test
prototypes of the systems.
4. Once these specifications were finalized, they were passed on to the production group, which
arranged for the fabrication& assembly of the products.
In August 2008, Beaumont introduced a new parallel system for product development in which a
"core team" of people assembled from all the critical functions–R&D, Marketing &
Sales, Product Engineering, Software Design, Regulatory, and Production–worked together
continuously to move a product from conceptual stage to final production. For every core team, a
project leader was designated to orchestrate its work, keep an eye on the complete project, secure
resources for the team, and serve as a liaison to senior management. Beaumont believed that the
project leader needed to have cross–functional expertise, a track record of high performance, and the
respect of his or her colleagues.
Most of MediSys 's professional employees embraced the cross–functional team design and parallel
development process. Conceptually, it fit their entrepreneurial and team–like
approach,

Designing A Bespoke Solution, Commercial Of The Shelf...
IT departments face the dilemma whether to purchase into a bespoke solution, commercial of the
shelf solution (COTS) or open sourcing, when sourcing new software. The chosen option should
meet the business and system requirements, as well as; understand the architectural requirements,
the current skill set of the development team, advances in technology, understand existing solutions
and advantages and disadvantages of each solution. These compose the six step process
recommended by techrepublic.com.
The business requirements must support the result. To obtain the key business requirements, the
right people within the business must be involved.
Techrepublic.com explains the core business requirements as;
"One that must be supported by the solution to continue. If a requirement can be only partially met
or not addressed by a solution, it is not a core requirement."
This definition shows the importance of the core requirements, without them being implemented,
the solution is ineffective.
The bespoke solution means that the business requirements are defined in house and it can be
explained to an out sourced company and so the solution is likely to be fit for the business.
A COTS solution is used by many companies, so has limitations as it leads to the business process
and requirements being dictated by the solution, which leads to restrictions impending growth and
development.
Open source solutions allow the company to have the COTS solution but mitigate any chance of the

Computer Programming And Software Design Essay
INTRODUCTION
An important, underrated and often overlooked tool for Computer Supported Collaborative Work,
henceforth abbreviated CSCW, is the revision control system or version control system, henceforth
abbreviated as RCS, or VCS, respectively. There are a plethora of RCS and VCS available from
which to choose. Within the field of computer programming and software design, the use of RCS or
VCS is a vital best practice, especially in development environments with many programmers,
developers, engineers, administrators, and managers. However, RCS or VCS can and should be used
wherever there are larger groups of CSCW regardless of the domain. Henceforth, RCS and VCS
shall be referred to as any generic revision or version control system, abbreviated as RVCS. The
significance of evaluating various RVCS becomes apparent by demonstrating and illustrating their
importance. Such evaluation is then used to produce or derive guidelines that streamline the
selection of the RVCS for a particular CSCW group.
WHAT EXACTLY IS RVCS?
One way to begin operationally defining RVCS is with the simple concept of artifacts and
deliverables produced, created, developed or engineered by the CSCW group. The sharing of such
artifacts is essential in the operations of the CSCW group (Schmidt, et. al., 2015). Typically, such
modern day artifacts or deliverables consist of documents, spreadsheets, diagrams, charts, tables,
graphs, reports, presentations, and other multimedia. In the domain of computer

Logical Vs. Physical Network Design Essay
Logical vs. Physical Network Design The typical Top–Down approach to network design uses a
systematic method to plan, design, and implement a new network. Generally, the Top–Down
methodology involves analysis of the business requirements and goals, development of the logical
design based on such goals, development of the physical design, and a phase for testing, optimizing,
and documenting the network design. This paper focuses on the activities performed to create a
logical design of a network and then goes on to explain how the physical design is created.

discussing the importance of planning and analysis. After all, the goal of ... Show more content on

He/she must perform a risk assessment of common applications to identify potential security
problems. The preliminary analysis will also answer questions such as who requires internet access,
email, or VPN which might implicate the need for firewalls on the network to protect against
unauthorized access to and from the outside of the network. Finally, the impact of any downtime
whether planned or unexpected needs to be addressed. How critical is it to the business to have near
100% uptime? This determination effects how protective measures such as redundancy, clustered
servers, disk arrays with RAID techniques, or multiple links between sites are built into the network.
Once the aforementioned information is gathered, the logical design process can commence. The
first step in logical design is selecting a network topology. Here, the overall structure of the network
is depicted by connecting lines between each node. Furthermore, the network segments along with
their scope, connection points, and placement of general inter–networking devices are defined.
Logical design also includes the creation of a layered hierarchal model which includes a core layer,
a distribution layer, and an access layer. The core layer is the backbone of the network and consists
of high–end equipment optimized for efficient packet flow. The distribution layer defines a
boundary between

The Challenges, Solutions, Models, Tools And Tools
Introduction
This paper presents a systematic literature review of the challenges, solutions, models, tools and an
example in Distributed Software Development (DSD). The objective is to collect and systematize
reported knowledge in terms of what are the difficulties in managing DSD projects, what are the
best practices to overcome these difficulties, and how existing models and tools support these
practices.
The DSD is a phenomenon with considerable interest from companies all over the world where the
stakeholders from different national and organizational cultures are involved in developing software.
As part of the globalization efforts currently pervading society, software project team members have
become geographically distributed. However, DSD is technologically and organizationally complex
and presents a variety of challenges to be managed by the software development team. [1]
As distributed environments have become the norm for software development, coordinating the
efforts of development teams has become one of the biggest challenges faced by the enterprise
today. It is hard to imagine any sizable development project managed without an underlying
software configuration management tool.Teams situated at different geographical locations,
including offshore, collaborate using communication technologies to develop interrelated software
modules that are integrated in shared project workspaces. The software design process involves
many iterative cycles of development

the processes towards improving the quality of the management software. The software will reflect
all the requirements defined by the customer, documented in the included requirements documents.
Further, included is an examination and evaluation of potential software development models for
identification of those best suited to develop the software. Finally, an explanation of the testing plan
utilized in testing the functionality of the system is included. Process Improvement The Library
Management System (LMS) must allow performance of all necessary procedures for librarians and
patrons. According to customer requirements, the software to be developed must consist of three
databases: Item's database (books, journals, magazines, newspapers, diploma thesis, etc) Patron's
database a small Access–based database with information about digital items, that College has
(software, music) integrated with Item's database The LMS must provide all necessary services for
databases such as creating, deleting, updating and searching information. Patrons need to easily
access to the web–based library site through the Internet or through the library's LAN–connected
computers, scattered throughout the library for sending request, receiving information about the
status of books, or renewing them. The design of product interface to be developed will be
supported by Microsoft IE,

Application Of A Software Development Model
Introducing RSDM into an organization 1.0 Introduction The value of software in meeting the
expected objectives depends on how it is designed. A good software design in an enterprise should
be based on quality. Designing and implementing the software system with the potential customers
in mind is one way of ensuring quality in this case. The Robust software Development Model
(RSDM) can be used for the purpose of defining trustworthy software as repetitive stages in the
development process. The Robust development Model works by recognizing the infrastructure, the
financial position, the customer needs as well as the leadership system of support of an enterprise
that are deemed fruitful for the implementation of Design for Trustworthy ... Show more content on

This top management team together with the CEO has the responsibility of examining the state of
their preparedness in an attempt to start on such an initiative. The entire exercise offers a chance to
consider the major challenges of an enterprise before staring the implementation process of DFTS
(Schwalbe 2013) The management team must thus be committed in the whole implementation
process given that it can be extremely challenging if the relevant competency together with the
enterprise leadership is not incorporated. The challenge comes in since the tools, approaches and the
principles of design for trust software are comparatively simple but at the same time are not simple
to implement. It is the desirable traits of leadership that can help in getting the best from the
individuals and groups that take part in the development and implementation of robust software. The
enterprise leadership or management team is also very significant in inspiring on personal level
especially in small enterprises and small teams for software development (Garton and Erika 2012).
2.1 Introduction of the enterprise extensive learning The first step of activity in letting an enterprise
to use Robust Software Development Model is the introduction of the enterprise extensive learning.
The enterprise extensive learning is significant in the building of foundations for constant learning
and enhancement.

Software Product Lines and Architecture
IV. SOFTWARE PRODUCT LINES
A software product line (SPL) is a set of software–intensive systems that share a common, managed
set of features satisfying the specific needs of a particular market segment or mission and that are
developed from a common set of core assets in a prescribed way.
Software product lines are emerging as a viable and important development paradigm allowing
companies to realize order–of–magnitude improvements in time to market, cost, productivity,
quality, and other business drivers. Software product line engineering can also enable rapid market
entry and flexible response, and provide a capability for mass customization.
The various product variants can be derived from the basic product family. The purpose is to reduce
the time and cost of production, and to increase software quality by reusing core assets. The general
process of product lines is based on the reusability of requirements, documentation, architecture and
components.
The process of product lines is based on the reusability of requirements, architecture and
components. It consists of two phases:
Domain Engineering.
Application Engineering. Fig.1 Software Product Lines Process
The above figure shows the three different aspects of the Software Product Line,
Core Assets – are the base used to produce new software products. They are defined on the basis of
preexisting products and future products. Core assets that evolve as new products are developed.

Software Reusability
Software reusability
TERM PAPER
Software reusability is generally considered a way to solve the software development crisis. When
we solve a problem we try to apply the solution to similar problems because that makes our work
easy and simple. Now in this paper I would like to cover important aspects of software reusability.
But one thing is for sure software reusability can improve software productivity. Software reuse has
become a topic of much interest in the software community due to its potential benefits, which
include increased product quality and decreased product cost and schedule. The most substantial
benefits derive from a product line approach, where a common set of reusable software assets act as
a base for subsequent ... Show more content on Helpwriting.net ...
And it's not just a technical issue; it is highly managerial in nature. As much as libraries of reusable
code and other assets are important, they will not be fully utilized without management and process
support of reuse.
Organization and Process
The classical software development process does not support reuse.[2] Reusable assets should be
designed and built in a clearly defined, open way, with concise interface specifications,
understandable documentation, and an eye towards future use. Typically, customer, client, and
contract projects are built as "one–time only," without reuse in mind, and tend to be tightly bound
within themselves, without the more robust open interfaces which ease the reuse process. Therefore,
in order to make the most of software reuse, the software development process must evolve to
include reuse activities.
A strong organizational foundation must exist for reuse to succeed, since domain engineering
involves a different way of looking at software products, called a product line approach. A product
line is a family of similar products addressing a particular market segment, or domain, and provides
a massive opportunity for reuse. With a reuse process in place, every

Design Patterns
Literature Review
Chapter One
Introduction
What is a Design Pattern?
A design pattern solves a problem within a given context. The solution that is offered by
implementing a pattern results in a system design structure, which balances the concerns of the
design problem in a manner most appropriate for the given context. In "Understanding and Using
Patterns in Software Development", Dirk Riehle and Heinz Zullighaven offer a rather nice definition
of what a design pattern is:
"A pattern is the abstraction from a concrete form which keeps recurring in specific non–arbitrary
contexts."
The ability to write good patterns is very difficult. A pattern should not only convey the facts about a
system, but it should also tell a story about ... Show more content on Helpwriting.net ...
The patterns described in the GoF book are illustrated in C++; a programming language that has
been declining in use over the last number of years, which limits the learning of patterns in today's
development environment where the dominant programming language taught and used, as far as
patterns are concerned is Java, although patterns can be implemented in any object orientated
programming language.
The patterns exhibited are described in very concise and restricted examples that lack a
comprehensive context in order for the reader to gain a full understanding of the use of the pattern in
question. The patterns throughout the book are also presented in isolation to each other which
hinders the illustration of pattern interaction and thus the full benefit to those wishing to learn how
to implement design patterns.
Allen Holub produced a book "Holub on Patterns – Learning Design Patterns by Looking at Code",
which detailed the use of design patterns while developing a game called "Game of Life. The Game
of Life is a cellular automation program, which begins with cells that are classed as either "alive" or
"dead". The idea is then that each cell follows a set of rules to determine which whether it can "live"
or whether it must "die".
Holubs' book, published in 2004 addressed some of the shortcomings of the GoF publication, such
as the patterns were now demonstrated in Java, which has become the favoured language of the
software development industry,

The Mvp Is Derived From Mvc Software Pattern, Pop And...
MVP Framework The MVP is derived from MVC software pattern, Pop and Altar 2014, that is
useful for the structuring of user interfaces. The MVP design pattern separates the view from its
presentation logic to allow each to be distinguished separately Qureshi and Sabir 2014, In MVP, the
view goes on to become an ultra–thin component whose function is just to be able to offer a
presentation to the user. The view captures and deals with the events increase by the user, though
forwarding these directly to the presenter who is aware on the means of treating them. The presenter
then communicates with the model, and coordinates with the view's controls directly so as to present
the data. The limitations of the MVP framework are listed below The pattern is complicated and
may be not really necessary for simple screens. The pattern is one more thing to be learnt for busy
developers: there's surely an overhead. It can be difficult to debug events that are being fired in
active Model–View–Presenter. The 'Passive View' version of Model–View–Presenter can result in a
particular amount of boilerplate code that has to be written in order to get the interface into the View
to work. 4. PROBLEM FORMATION AND OBJECTIVES This research is concerned with
analyzing the systematic approach, Importance of Reusability, Risk Factor, Complexity of Process

The concept of having re–usable software and hardware components which can be used for product
developments have been in vogue for quite some time but in form of frameworks conforming to
different standards which need good learning time from their users perspective. À la carte Product
Development aims at having a single portal which can span across the lifecycle of product
development. The portal would have all the interactions and modules that can be made available as a
service.
The thought process aims to bring down new product development to something as simple as
selecting client interfacing UI pages, logging services, databases, cloud based hardware
infrastructure, support management workflows, weekly maintenance activities as simple services
which can be selected from a list in the dropdown of the menu at the À la carte Product
Development portal . Once a confirmation to avail these services in the product is entered, the
hardware and software modules would auto–configure and export to produce a ready to deploy

application.
The process of having loosely coupled hardware and software components help in making the
objective of robust scalability of products a

information; going from their name to their credit card information. In fact, with the evolution of
technology (most importantly the increase in access to the internet), E–business or E–commerce has
been pushed to a new level. Today, customers want to be able to access services at anytime,
anywhere. This has led to the development of applications that can be executed on distributed
environment or in real time such as Web based applications or a Client server application. Hence,
secure software development is not an option but a must that software engineers have to put in
practice so that data integrity can be guaranteed to users. The ... Show more content on

As a consequence, an increasing number of users and organizations have expressed the need of more
robust systems and applications. Hence, this fact implies incorporating an effective security stage
into the development life cycle in order to be able to efficaciously assess security issues. Secure
software development cycle not only encompass the development and the implementation of a
software but, also the processes that guaranty that a piece of software meets its requirement while
minimizing expositions to malicious threats that could expose users and minimizing the cost of
development (Microsoft.com) Planning and requirements Requirement analysis is probably the most
important and more complex process in the Software Development Life Cycle framework. In Secure
software development, senior developers, together with stakeholders, not only discuss the
fundamental of the SDLC such as project planning, assessing product feasibility studies and
management requirements, but also define set of activities to formalize the security requirements for
a specific product release (SafeCode source). These activities are defined using use cases, strategic
company security policies, defined security improvement goals and customers' inputs. This implies
identifying functional and non–functional requirements and applying a high risk assessment on them
in order to determine security risks and to prioritize security requirements as per threat and risk

Intro to System Analysis and Design
Introduction to System Analysis and Design 1. INTRODUCTION Systems are created to solve
problems. One can think of the systems approach as an organized way of dealing with a problem. In
this dynamic world, the subject System Analysis and Design, mainly deals with the software

System Analysis also includes sub–dividing of complex process involving the entire system,
identification of data store and manual processes. The main points you are to discuss in your papers
regarding system analysis are: Specification of what the new system is to accomplish based on the
user requirements. Functional hierarchy showing the functions to be performed by the new system
and their relationship with each other. Function network which are similar to function hierarchy but
they highlight those functions which are common to more than one procedure. List of attributes of
the entities – these are the data items which need to be held about each entity (record) (d) System
Design Based on the user requirements and the detailed analysis of a new system, the new system
must be designed. This is the phase of system designing. It is a most crucial phase in the
development of a system. Normally, the design proceeds in two stages: preliminary or general
design Structure or detailed design Preliminary or general design: In the preliminary or general
design, the features of the new system are specified. The costs of implementing these features and
the benefits to be derived are estimated. If the project is still

Logical vs. Physical Network Design The typical Top–Down approach to network design uses a
systematic method to plan, design, and implement a new network. Generally, the Top–Down
methodology involves analysis of the business requirements and goals, development of the logical
design based on such goals, development of the physical design, and a phase for testing, optimizing,
and documenting the network design. This paper focuses on the activities performed to create a
logical design of a network and then goes on to explain how the physical design is created.

This also covers a portion of the logical design process of addressing the scalability requirements.
Figure 1. A three–layered hierarchal design model
Physical Network Design Whereas the logical design of the network most accurately reflects the
needs of the business by depicting network structure with regards to the organizational units and
requirements, the physical design is more concerned with distance, cabling, and connectivity issues.
Generally, a physical network is tied very closely with the building infrastructure and floor plan. It
depicts the physical connections of the devices and no other relationships among them. In contrast,
the logical network establishes the boundaries of subnets as a concept, not a physical connection,
using switching and VLAN techniques. The physical network design would normally follow the
logical design in a typical top–down approach. The decisions made during the physical design of the
network involve the implementation suggestions of specific equipment and technology. One such
choice is the overall LAN technology such as Ethernet, FDDI, or Token Ring. The topology chosen
in the logical design usually makes this decision apparent. Also, the determination of devices such
as whether to use hubs or routers is made, how many are required, how many

Software Design Of A Computer Based System
A key requirement of the software design of a computer–based system is to transform basic
requirements into an architecture that describes the software 's top–level structure and identifies its
components. Accomplishment of this requirement is through architectural design, providing a
blueprint for developing the framework of the software (Mattsson, Lundell, Lings, & Fitzgerald,
2009). The establishment of the framework involves examining the software requirements document
and designing a model for providing necessary implementation details. The details specify
components of the system along with all inputs, outputs, functions, and the interactions between the
components. This paper includes a description of the architectural design of a computer–based
system that has transform characteristics, and includes a data flow diagram with process narrative,
and evaluation of the architectural design. Further, an assessment of the structuring requirements
associated with software architecture is included.
Architectural Design & Structure An architectural design performs key functions, and is of crucial
importance in software engineering during the phase of software development where the essential
requirements of reliability, cost, and performance are determined. Architectural design provides the
definition of the abstraction level at which the software design specifies both the functional and
performance behaviors of the system, and the guidelines for enhancing the system by
