Incorporating A DesignOps Approach Into Solution ArchitectureAlan McSweeney
Solution architecture and design is concerned with designing new (IT) solutions to resolve problems or address opportunities . In order to solve a problem, you need sufficient information to understand the problem. If you do not understand the scope of the required solution you cannot understand the risks associated with the implementation approach.
Getting the solution wrong can be very expensive. The DesignOps approach is a unified end-to-end view of solution delivery from initial concept to steady state operations. It is a design-to-operations approach identifying all the solution design elements needed to ensure the delivery of a complete solution.
Solution architecture and design teams are becoming larger so more co-ordination, standardisation and management is required. The increasing focus on digital transformation increases the need for improved design as business applications are exposed outside the organisation. Solution complexity is increasing. The aim of the DesignOps approach is to improve solution design outcomes.

The document provides an example script to validate the file type and size, and also shows how to permanently save the uploaded file by copying it from the temporary location.
Cookies are small files stored on a user's computer that identify the user each time they visit a website. PHP allows you to create and retrieve cookie values. The setcookie() function is used to create a cookie by specifying a name, value, and expiration time. Cookie values are stored in the $_COOKIE superglobal array and can be accessed to retrieve the value. Cookies can be deleted by setting an expiration time in the past. If browsers do not support cookies, other methods like forms can be used to pass data between pages.
PHP sessions allow storing and retrieving user-specific information across multiple pages using a unique identifier. Sessions start with the session_start() function and variables are stored using the $_SESSION superglobal array. Common uses include tracking user logins, shopping carts, or page views. Sessions are temporary and deleted when the user closes their browser.
PHP provides default error handling that displays error messages to the browser. It is important to implement custom error handling in scripts to avoid unprofessional errors being displayed and security risks. This document discusses different PHP error handling methods like using die() statements, creating custom error handlers with the set_error_handler() function, and triggering errors with trigger_error(). It also covers error logging methods like sending error messages via email with error_log().
The document discusses the benefits of exercise for mental health. It notes that regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise has also been shown to boost self-esteem and can serve as a healthy way to manage stress.
The document discusses security concepts related to information technology security. It defines key terms like vulnerability, threat, and attack and explains how social engineering exploits human trust and weaknesses in security to gain access to confidential information. The document outlines different types of social engineering like phishing and shoulder surfing and provides examples of phishing emails. It describes how to protect against social engineering attacks and defines identity theft.
This document provides an overview of key concepts in information security from a lecture on security concepts. It defines security as keeping the possibility of threats low, and discusses specialized security areas like physical, personal, communications, network, and data security. It also defines computer security as protecting computer systems, hardware, software, data and information from threats. The document then examines common security vulnerabilities, threats, and the vulnerability-threat-control paradigm. It discusses goals of security like confidentiality, integrity and availability.
CP 121 introduces database systems. The lecture covers file-based systems, the database approach, common database uses, users, DBMS components and functions, and advantages and disadvantages of databases. Key points include: File-based systems are limited but the database approach offers data sharing and consistency. A DBMS manages data storage, transactions, integrity, security and more. Database users include administrators, designers, developers and end users who access data through applications.
The document provides instructions for a weekly lab assignment on algorithms and flow charts. Students are asked to define problems, algorithms, flow charts, and procedures. They must also describe symbols used in flow charts and rules for constructing them. Finally, students are instructed to write an algorithm and draw a flow chart to calculate the total number of mangoes two twins have if each bought three mangoes and they share a bag.
Graph theory has many applications in modeling real-world networks like computer networks and chemical compounds. It studies graphs, which are collections of vertices connected by edges. A graph can be represented using an incidence matrix or adjacency list/matrix. Connectivity refers to reachability between vertices by traversing edges. The shortest path problem finds the minimum weight path between vertices in a weighted graph. Planar graphs can be drawn in a plane without edge crossings, and satisfy Euler's formula relating vertices, edges, and regions. Graph coloring assigns different colors to connected elements like vertices or edges.
This document outlines the laws of algebra for propositional logic, including identities, commutative laws, associative laws, distributive laws, De Morgan's laws, and other logical equivalences. It defines tautologies as statements that are always true regardless of the truth values assigned to variables, and contradictions as statements that are always false. Examples of truth tables are provided to demonstrate tautologies, contradictions, and logical equivalence between statements. The document concludes by posing questions to classify logic formulas as tautologies, contradictions, or contingencies using truth tables and the laws of propositional logic.
This document provides an introduction to propositional logic and proofs in discrete mathematics. It defines basic concepts like propositions, propositional variables, logical connectives (negation, conjunction, disjunction, conditionals, biconditionals), and truth tables. Examples are provided to illustrate these concepts, such as determining the negation or conjunction of given propositions, and constructing truth tables. The document lays the groundwork for understanding logic and proofs in discrete mathematics.
The document provides an overview of the internet and how it works. It discusses that the internet connects hundreds of thousands of networks globally through lines. It can be used to send emails, files, participate in discussions, and surf the web. The world wide web consists of linked web pages containing text and images. People can access the internet through schools, businesses, or internet service providers using browsers like Firefox or Internet Explorer. Each device on the internet has a unique IP address and domain names are used to locate websites.
This document provides an introduction to information systems concepts from a class taught by Augustino Mwogosi. It discusses key perspectives on information systems including how they support business processes, decision making, and competitive strategies. It also outlines the core components of information systems including data, people, procedures, hardware, software and how they work together.
This document outlines the course outline and content for a development perspectives course. It begins with an introduction to the course description and objectives, which aim to analyze development theories and their implications. It then provides an overview of the key topics to be covered, including theories of social economic development, development ethics, global development agendas, governance, conflict and peace, decentralization, and gender and development. The course content section provides further details on the individual topics to be examined, such as Marxist theory, modernization theory, poverty, and health.
This document discusses gender issues and development. It begins by defining key concepts like gender, sex, gender equality, and gender equity. It then discusses several gender and development issues such as life expectancy, population ratios, education, health, and employment. Specifically, it notes that women face disadvantages in these areas, such as higher illiteracy rates and school dropout rates compared to men. It also discusses three theories related to women's role in development: Women in Development (WID), Women and Development (WAD), and Gender and Development (GAD). WID focused on integrating women into development projects while WAD and GAD also aimed to challenge existing gender roles and relations.

ViewShift: Hassle-free Dynamic Policy Enforcement for Every Data LakeWalaa Eldin Moustafa
Dynamic policy enforcement is becoming an increasingly important topic in today’s world where data privacy and compliance is a top priority for companies, individuals, and regulators alike. In these slides, we discuss how LinkedIn implements a powerful dynamic policy enforcement engine, called ViewShift, and integrates it within its data lake. We show the query engine architecture and how catalog implementations can automatically route table resolutions to compliance-enforcing SQL views. Such views have a set of very interesting properties: (1) They are auto-generated from declarative data annotations. (2) They respect user-level consent and preferences (3) They are context-aware, encoding a different set of transformations for different use cases (4) They are portable; while the SQL logic is only implemented in one SQL dialect, it is accessible in all engines.

4. Systems Development
What is a system?
A collection of related components that interact to
perform a task in order to accomplish a goal.
Systems development (systems analysis and
design) is the process of creating systems,
developing them, and maintaining or enhancing
them.
5. What is system development life cycle
(SDLC)?
• 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.
2/6/2020 prepared by Mwahasanga Hissan d 5
6. System analyst
• The key person in the SDLC is the systems
analyst, who analyzes the business situation,
identifies opportunities for improvements,
and designs an information system to
implement the improvements.
• As a systems analyst, you will work as a team
with a variety of people, including business
and technical experts.
2/6/2020 prepared by Mwahasanga Hissan d 6
7. Cont…..
• It is important to remember that the primary objective
of the systems analyst is not to create a wonderful
system.
• The primary goal is to create value for the organization,
which for most companies means increasing profits.
• Many failed systems were abandoned because the
analysts tried to build a wonderful system without
clearly understanding how the system would support
the organization’s goals, improve business processes,
and integrate with other information systems to
provide value.
2/6/2020 prepared by Mwahasanga Hissan d 7
8. Systems Analyst Skills
• Systems analysts must understand how to apply
technology to solve business problems. In addition,
systems analysts may serve as change agents who
identify the organizational improvements needed, design
systems to implement those changes, and train and
motivate others to use the systems.
• Understanding what to change, knowing how to change
it, and convincing others of the need for change require
a wide range of skills. These skills can be broken down
into six major categories: technical, business, analytical,
interpersonal, management, and ethical.
2/6/2020 prepared by Mwahasanga Hissan d 8
9. Summary of skills
• Analysts must have the technical skills to understand the organization’s existing technical
environment, the new system’s technology foundation, and the way in which both can be fit
into an integrated technical solution.
• Business skills are required to understand how IT can be applied to business situations and
to ensure that the IT delivers real business value.
• Analysts are continuous problem solvers at both the project and the organizational level,
and they put their analytical skills to the test regularly.
• Often, analysts need to communicate effectively, one-on-one with users and business
managers (who often have little experience with technology) and with programmers (who
often have more technical expertise than the analyst does).
• They must be able to give presentations to large and small groups and to write reports. Not
only do they need to have strong interpersonal abilities, but they also need to manage
people with whom they work, and they must manage the pressure and risks associated with
unclear situations.
• Finally, analysts must deal fairly, honestly, and ethically with other project team members,
managers, and system users. Analysts often deal with confidential information or
information that, if shared with others, could cause harm (e.g., dissent among employees); it
is important for analysts to maintain confidence and trust with all people.
2/6/2020 prepared by Mwahasanga Hissan d 9
10. Systems Analyst Roles
• The systems analyst role focuses on the IS issues
surrounding the system.
• This person develops ideas and suggestions for
ways that IT can support and improve business
processes, helps design new business processes
supported by IT, designs the new information
system, and ensures that all IS standards are
maintained.
• The systems analyst will have significant training
and experience in analysis and design and in
programming
2/6/2020 prepared by Mwahasanga Hissan d 10
11. Alleviating the Problems in
Systems Development
Elimination of the causes of system failure lie in
1. the application of methodologies
2. modeling tools
3. techniques
4. project management techniques
to design and build IS that not only meet the needs of the
users, but also are delivered on time and within budget.

20. PHASES AND THEIR RELATED
DOCUMENTATIONS
2/6/2020 prepared by Mwahasanga Hissan d 20
21. How we start?
• In many ways, building an information system is similar to
building a house. First, the owner describes the vision for
the house to the developer. Second, this idea is
transformed into sketches and drawings that are shown to
the owner and refined (often, through several drawings,
each improving on the other) until the owner agrees that
the pictures depict what he or she wants. Third, a set of
detailed blue- prints is developed that presents much more
specific information about the house(e.g., the layout of
rooms, placement of plumbing fixtures and electrical
outlets, and so on). Finally, the house is built following the
blueprints—and often with some changes and decisions
made by the owner as the house is erected.
2/6/2020 21prepared by Mwahasanga Hissan d
22. Major Attributes of the Life Cycle
• The project
– Moves systematically through phases where
each phase has a standard set of outputs
– Produces project deliverables
– Uses deliverables in implementation
– Results in actual information system
– Uses gradual refinement
2/6/2020 prepared by Mwahasanga Hissan d 22
23. Project Phases
1. Planning (Why build the system? How should the
team go about building it?)
2. Analysis (Who uses system, what will it do, where and
when will the system be used?)
3. Design (How will the system work?)
4. Implementation or deploy (System delivery)
The system is ready to be deployed and installed in customer’s premises, ready to become
running, live and productive, training may be required for end users.
5. System Testing and Integration
Testing is becoming more and more important to ensure customer’s
satisfaction, and it requires no knowledge in coding, hardware configuration or
design.
2/6/2020 prepared by Mwahasanga Hissan d 23
24. Project Phases cont.…
6. System Maintenance
-Periodic maintenance for the system will be carried out to make sure that
the system won’t become obsolete, (outdated)
-Replacing the old hardware and continuously evaluating system’s
performance,
-Providing latest updates for certain components to make sure it meets the
right standards and the latest technologies to face current security threats.
2/6/2020 prepared by Mwahasanga Hissan d 24
25. Phases in summary
• Building an information system using the SDLC
follows a similar set of four fundamental
phases: planning, analysis, design, and
implementation .
2/6/2020 25prepared by Mwahasanga Hissan d
26. Planning
• The planning phase is the fundamental
process of understanding why an information
system should be built and determining how
the project team will go about building it.
It has the following steps:
• project initiation
• project management
2/6/2020 26prepared by Mwahasanga Hissan d
27. project initiation
• During project initiation, the system’s business value to the
organization is identified—how will it lower costs or
increase revenues. The IS department works together with
the person or department generating the request (called
the project sponsor) to conduct a feasibility analysis. The
feasibility analysis examines key aspects of the proposed
project:
• The technical feasibility (Can we build it?)
• The economic feasibility (Will it provide business value?)
• The organizational feasibility (If we build it, will it be used?)
2/6/2020 27prepared by Mwahasanga Hissan d
28. Individual assignment
• Why business case? And what are its
importance?
2/6/2020 prepared by Mwahasanga Hissan d 28
29. project management
• Once the project is approved, it enters project
management. During project management,
the project manager creates a work plan,
staffs the project, and puts techniques in place
to help the project team control and direct the
project through the entire SDLC.
• The deliverable for project management is a
project plan that describes how the project
team will go about developing the system.
2/6/2020 29prepared by Mwahasanga Hissan d
30. Planning summary
• Identifying business value
• Analyze feasibility
• Develop work plan
• Staff the project
• Control and direct project
2/6/2020 prepared by Mwahasanga Hissan d 30
31. Analysis
• The analysis phase answers the questions of who will use the system,
what the system will do, and where and when it will be used.
• During this phase, the project team investigates any current system(s),
identifies improvement opportunities, and develops a concept for the new
system.
This phase has three steps:
1. study of the current system (called the as-is system) and its problems,
and envisioning ways to design a new system (called the to-be system).
2. The next step is requirements gathering (e.g., through interviews, group
work- shops, or questionnaires).
3. system proposal, which is presented to the project sponsor and other
key decision makers (e.g., members of the approval committee) who will
decide whether the project should continue to move forward.
2/6/2020 31prepared by Mwahasanga Hissan d
33. Design
• The design phase decides how the system will
operate in terms of the hardware, software, and
network infrastructure that will be in place. i.e
the user interface, forms, and reports that will be
used; and the specific programs, databases, and
files that will be needed.
• Although most of the strategic decisions about
the system are made in the development of the
system concept during the analysis phase, the
steps in the design phase determine exactly how
the system will operate.
2/6/2020 33prepared by Mwahasanga Hissan d
34. Design summary
• Design selection
• Architecture design
• Interface design
• Data storage design
• Program design
2/6/2020 prepared by Mwahasanga Hissan d 34
35. Implementation
• The final phase in the SDLC is the
implementation phase, during which the
system is actually built (or purchased, in the
case of a packaged software design and
installed).
• This is the phase that usually gets the most
attention, because for most systems it is the
longest and most expensive single part of the
development process.
2/6/2020 35prepared by Mwahasanga Hissan d
36. Three phases of implementation
1. System construction is the first step. The system is built and
tested to ensure that it performs as designed. Since the cost of fixing
bugs can be immense, testing is one of the most critical steps in
implementation. Most organizations spend more time and attention
on testing than on writing the programs in the first place.
2. The system is installed. Installation is the process by which the
old system is turned off and the new one is turned on. There are
several approaches that may be used to convert from the old to the
new system. One of the most important aspects of conversion is the
training plan, used to teach users how to use the new system and
help manage the changes caused by the new system.
3. The analyst team establishes support plan for the system.
This plan usually includes a formal or informal post-implementation
review, as well as a systematic way for identifying major and minor
changes needed for the system.
2/6/2020 prepared by Mwahasanga Hissan d 36
37. Implementation
• Construction
– Program building
– Program and system testing
• Installation
