FRAMEWORKS BETWEEN COMPONENTS AND OBJECTSacijjournal
Before the emergence of Component-Based Frameworks, similar issues have been addressed by other
software development paradigms including e.g. Object-Oriented Programming (OOP), ComponentBased Development (CBD), and Object-Oriented Framework. In this study, these approaches especially
object-oriented Frameworks are compared to Component-Based Frameworks and their relationship are
discussed. Different software reuse methods impacts on architectural patterns and support for
application extensions and versioning. It is concluded that many of the mechanisms provided by
Component-Based Framework can be enabled by software elements at the lower level. The main
contribution of Component-Based Framework is the focus on Component development. All of them can be
built on each other in layered manner by adopting suitable design patterns. Still some things such as
which method to develop and upgrade existing application to other approach.
This document provides an overview of software engineering concepts covered in lecture notes. It discusses the software development life cycle (SDLC) which includes key stages like requirements gathering, design, coding, testing, integration and maintenance. The SDLC framework aims to develop software efficiently using a well-defined process. Software engineering principles like abstraction and decomposition are used to reduce complexity when developing large programs.
Software connectors are architectural elements that model interactions between components. They define rules governing interactions and provide channels for transferring control and data. In software systems, connectors are often not explicitly implemented but distributed across code, while in architectures they are first-class entities with identities. Treating connectors independently from components supports separation of interaction from computation and facilitates software evolution.
A reliability estimation framework for OO design complexity perspective has been developed inthis paper. The proposed framework correlates the object oriented design constructs with complexity and also correlates complexity with reliability. No such framework has been available in the literature that estimates software reliability of OO design by taking complexity into consideration. The framework bridges the gap between object oriented design constructs, complexity and reliability. Framework measures and minimizes the complexity of software design at the early stage of software development life cycle leading to a reliable end product. Reliability and complexity estimation models have been proposed by following the proposed framework. Complexity estimation model has been developed which takes OO design constructs into consideration and proposed reliability estimation models take complexity in consideration for estimating reliability of OO design.

Improved Strategy for Distributed Processing and Network Application Developm...Editor IJCATR
The complexity of software development abstraction and the new development in multi-core computers have shifted the burden of distributed software performance from network and chip designers to software architectures and developers. We need to look at software development strategies that will integrate parallelization of code, concurrency factors, multithreading, distributed resources allocation and distributed processing. In this paper, a new software development strategy that integrates these factors is further experimented on parallelism. The strategy is multidimensional aligns distributed conceptualization along a path. This development strategy mandates application developers to reason along usability, simplicity, resource distribution, parallelization of code where necessary, processing time and cost factors realignment as well as security and concurrency issues in a balanced path from the originating point of the network application to its retirement.
Model driven process for real time embeddedcaijjournal
Embedded systems shape our world nowadays. It’s almost impossible to imagine our day to day life without
it. Examples can include cell phones, home appliances, energy generators, satellites, automotive
components …etc. it is even far more complex if there are real-time and interface constraints.
Developing real-time embedded systems is significantly challenging to developers. Results need not be only
correct, but also in a timely manner. New software development approaches are needed due to the
complexity of functional and non-functional requirements of embedded systems.
Due to the complex context of embedded systems, defects can cause life threatening situations. Delays can
create huge costs, and insufficient productivity can impact the entire industry. The rapid evolution of
software engineering technologies will be a key factor in the successful future development of even more
complex embedded systems.
Software development is shifting from manual programming, to model-driven engineering (MDE). One of
the most important challenges is to manage the increasing complexity of embedded software development,
while maintaining the product’s quality, reducing time to market, and reducing development cost.
MDE is a promising approach that emerged lately. Instead of directly coding the software using
programming languages, developers model software systems using expressive, graphical notations, which
provide a higher abstraction level than programming languages. This is called Model Based Development
(MBD).
Model Based Development if accompanied by Model Based Validation (MBV), will help identify problems
early thus reduce rework cost. Applying tests based on the designed models not only enable early detection
of defects, but also continuous quality assurance. Testing can start in the first iteration of the development
process.
As a result of the model based approach, and in addition to the major advantage of early defects detection,
several time consuming tasks within the classical software development life cycle will be excluded. For
embedded systems development, it’s really important to follow a more time efficient approach.

This document summarizes an approach for preserving JavaScript state when migrating web applications across multiple devices. The key challenges addressed are maintaining the JavaScript state, including values of variables, function references, timers and dates. The solution uses a migration server to capture the current page state, including the DOM and JavaScript variables, and generate a new version of the page optimized for the target device while maintaining the same interactive state. Special techniques are required to handle JavaScript object references and circular references during state serialization and restoration.
The document discusses software connectors, which are architectural elements that model interactions between components. Connectors provide interaction ducts to transfer control and data between components.

It proposes that web services allow non-technical people to construct complex business software by assembling reusable software components/services. However, there are still challenges to address like how to take abstract concepts into software and ensure quality attributes like performance and security. The document presents a "separation continuum" model to understand the different elements that make up business systems from abstract requirements to software implementation. It argues that application assembly using independently developed web services is feasible if standards are followed and the right assembly tools are available.
[2015/2016] Software systems engineering PRINCIPLESIvano Malavolta
This presentation is about a lecture I gave within the "Software systems and services" immigration course at the Gran Sasso Science Institute, L'Aquila (Italy): http://cs.gssi.infn.it/.
http://www.ivanomalavolta.com
YouCreate is a collaborative software development platform that allows teams to develop web applications together. It uses a visual flowcharting approach to code development that does not require technical knowledge. The platform stores all project elements in a central repository and allows different users, such as designers, developers and project managers, to collaborate simultaneously. Code generators then translate the visual code into code for different platforms like Java and C++.
The document provides an overview of key concepts in web engineering and the web engineering process. It discusses that early web development relied on informality, urgency, intuition and art but that as web apps become larger and more complex, some degree of requirements gathering, planning and proven patterns are needed. It defines web engineering as an agile yet disciplined framework for building industry-quality web apps. The core activities of the web engineering process are communication, planning, modeling, construction, deployment and adaptation of the framework based on the specific project.
Using Evolutionary Prototypes To Formalize Product RequirementsArnold Rudorfer
Boundary objects are artifacts that facilitate
communication and interaction between people or groups
functioning in different domains. Software engineers, user
interface designers and usability specialists have different
domain knowledge, different terminologies, and shared
terms with different, distinct meanings. Boundary objects
can help assist the process of designing software by
providing a common interface for communication between
professionals in different domains. The Software
Engineering department and User Interface Design Center
at Siemens Corporate Research used an evolutionary
prototype as a boundary object to help elicit product
requirements from their client, Siemens Medical Solutions.
This enhanced communication with the client and between
groups at SCR. This paper describes how the evolutionary
prototype functioned as a boundary object and how it
allowed software engineering processes and humancomputer
interaction methods to proceed concurrently
without the need for well-defined interaction points.
Software engineering Questions and AnswersBala Ganesh
1. Risk management is the process of identifying, addressing, and eliminating potential problems that could threaten the success of a project before they cause damage. This includes issues that could impact cost, schedule, technical success, product quality, or team morale.
2. HIPO (Hierarchical Input Process Output) diagrams were developed at IBM as a design representation and documentation aid. They contain a visual table of contents, overview diagrams, and detailed diagrams.
3. Software maintenance is any work done to modify software after it is operational, such as fixing errors, adding capabilities, removing obsolete code, or optimizing performance. It aims to preserve the software's value over time as requirements, users, and technology change. M

The document discusses agile software development and extreme programming (XP). It defines agility as effective response to change through communication, flexible planning, and incremental delivery. XP emphasizes rapid delivery, customer collaboration, unit testing, pair programming, and refactoring code. The debate around XP includes whether its informal requirements and lack of formal design can accommodate complex systems with changing needs. Other agile processes mentioned include Scrum, DSDM, Crystal, and Agile Modeling.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.

4.1.1 Multi Layer/Tier Architectures(TopDown)
Layers : "Logical layers are merely a way of organizing your code. Typical layers include Presentation, Business and
Persistence ”the same as the traditional 3tier model. But when we are talking about layers, we are only talking about
logical organization of code. In no way is it implied that these layers might run on different computers or in different
processes on a single computer or even in a single process on a single computer. All we are doing is discussing a way
of organizing a code into a set of layers defined by specific function"[5][6]. Typical layers are:
Presentation Layer : User Interface, the main function is to translate the tasks and results to something the
user can understand.
Business Layer : Coordinates the application processes commands and make logical decisions and
evaluations, and performs calculations. I moves and processes data between the two surrounding layers.
Persistence Layer : Information store and retrieval from data base system.
Tiers: "Physical tiers however, are only about where the code runs. Specifically, tiers are places where layers are
deployed and where layers run. In other words, tiers are the physical deployment of layers".[5][6].

4.1.2 Object Oriented Architectures (OO)
An objectoriented system[7] is composed of objects. The behavior of the system results from the collaboration of those
objects. Collaboration between objects involves them sending messages to each other. Sending a message differs from
calling a function in that when a target object receives a message, it decides on its own what function to carry out to
service that message. The same message may be implemented by many different functions, the one selected depending
on the state of the target object. Object Oriented Systems[8] are constructed as structured collections of abstract data
types implementations.
4.1.3 Service Oriented Architecture s (SOA)
In software engineering, a serviceoriented architecture is a set of principles and methodologies for designing and
developing software in the form of interoperable services. These services are welldefined business functionalities that
are built as software components (discrete pieces of code and/or data structures) that can be reused for different
purposes. SOA design principles are used during the phases of systems development and integration. [9]
4.1.4 Model View Controller (MVC) Architecture
A model view controller[9] (design pattern), separates concerns in tree roles:
Model: A model notifies its associated views and controllers when there has been a change in its state.
This notification allows the views to produce updated output, and the controllers to change the available
set of commands.
View: A view requests from the model the information that it needs to generate an output representation.
Controller: A controller can send commands to its associated view to change the view's presentation of the
model (e.g., by scrolling through a document). It can send commands to the model to update the model's
state (e.g., editing a document).
4.1.5 Model View Presenter (MVP) Architecture
ModelViewPresenter is a derivative of the ModelViewController (MVC) software pattern, also used mostly for building
user interfaces. In MVP the presenter assumes the functionality of the middleman (played by the controller in MVC). In
MVP, all presentation logic is pushed to the presenter. Eventually, the model becomes strictly a domain model.
MVP is a user interface design pattern engineered to facilitate automated unit testing and improve the separation of
concerns in presentation logic:
Model: is an interface defining the data to be displayed or otherwise acted upon in the user interface.
View: is a passive interface that displays data (the model) and routes user commands (events) to the
