Study Notes

Software Development, Systems Analysis Design

A computer application (app) is a software program that performs a specific set of functions on a computing device.
An app typically has a modest scope, focusing on a single task.
An information system is a set of interconnected components that collect, process, store, and provide information to support business tasks.
Information systems are broader in scope than applications, encompassing databases and related manual processes.

Systems Analysis and Design

Systems analysis and design are crucial components of the systems development lifecycle (SDLC).
Systems analysis involves understanding the problem from the user's perspective.
Systems design involves describing the solution to the problem from the user's perspective.

System Development Lifecycle (SDLC)

The SDLC is the complete process for building, launching, and maintaining an information system.
It encompasses six main activities: identifying the problem/need, planning and monitoring the project, discovering and understanding the details, designing the system components, building, testing, and integrating components, and completing system tests and deploying the solution.
Characteristics of a project include implementation, risks, purpose, scope, timescales, and financials.

Software Models

Software models are prototypes of software applications that show the functionality but may not fully depict the original software's logic.
Agile and iterative development are common methodologies.

Agile Development

Agile development emphasizes flexibility to accommodate changing requirements during development.

Iterative Development

Iterative development builds systems incrementally through repeated cycles of iterations to refine and add features.

Agile/Iterative Development

Iterative development using sprints (increments of 2 weeks to 2 months) efficiently delivers systems, concentrating on quick delivery and accommodating emerging requirements.
- Scrum is a framework that helps teams work together to execute development efforts efficiently.
- Extreme Programming (XP) promotes the incremental development process using short development cycles to improve productivity and address new customer requirements.
- Feature-Driven Development (FDD) concentrates on delivering software features that satisfy specific client needs.
- Kanban is an agile management methodology focused on continuous improvement.

Information Systems Development Process/Methodology

A set of comprehensive guidelines helps carry out the SDLC's activities, creating a structured process.
Frameworks such as Waterfall, Spiral, Agile, Iterative, Scrum, XP, and FDD are used.

Visual Project Management

The Kanban board visualizes project workflows using cards that move through different stages.

Core SDLC Process 3: Discover and Understand Details

Do preliminary fact-finding to understand the need and requirements
Develop a list of use cases and a use case diagram, and develop a preliminary list of classes and a class diagram

Core Process 2: Plan the Project

Determine all major components required in the solution
Define the iterations and assign the functions to each iteration, plan one iteration, determine the team members and their responsibilities, and create a work breakdown structure

Core Process 1: Discover and Understand

Meeting with the department manager and purchasing agents to determine use cases and define info needs
Design the input, output, and reporting screens
Design of the database and overall architecture
Detailed program design and build phase

Models and Modeling

A model is a representation of aspects of a system.
Textual models (descriptions), graphical models (diagrams), and mathematical models (formulas) are used.
The Unified Modeling Language (UML) provides a standard for graphical modeling for information systems.

Use Cases

Use cases describe the ways users interact with a system to achieve a goal.
Describing the type of user, specific goal or action, and the expected outcome or benefit helps define use cases.
Use cases are helpful for both small and complex applications, and help document internal processes and steps.
- Steps (identify potential users, classify users by role and organizational level, produce a list of user goals) help define a list of use cases.
Events, including external, temporary, and state events help describe use cases more completely
Use case diagrams and use case descriptions are important tools for modeling use cases for better communication within a group.
Templates use keywords like <<Given…When…Then>> to give a step-by-step explanation of each use case

Activity Diagrams

Activity diagrams graphically detail user or system activities and the flow within a use case.

System Analysis and Design Models

System Diagrams illustrate workflows and business processes
Class Diagrams, Sequence Diagrams, Communication Diagrams, Activity Diagrams, State Diagrams and others are used to analyze relationships and process actions, and describe systems.

Domain Analysis and Design Models

Focuses on identifying classes and describing their attributes, relationships, and interactions.
Brainstorming techniques, noun identification, and use cases are used.
Different types of domain classes are discussed including tangible things, roles, organizational units, devices, sites or locations, and events/instances.
Three techniques for identifying classes are given: Brainstorming, Noun, and Event Decomposition

Domain Class Diagrams / Relationships

Include classes with their Attributes and Associations (using the UML notation)

Domain Class Diagrams / Relationships and Use Cases

Use case diagrams include actors and use cases that relate to the domain classes.
The use cases are part of the domain and interaction.
Use case activities lead to interaction details – for example, communication diagrams and sequences,

Design Principles

Object responsibility, separation of responsibilities, protection from variations, indirection, cohesion, and coupling.

System Sequence Diagrams (SSD)

SSDs illustrate inputs and outputs to each use case as messages from the object.

Use Cases and CRC Cards

Using CRC cards to improve design by emphasizing communication, responsibilities, and collaborations.

Design Models

Focuses on design models from requirements models, use case, designs and analysis, and implementation.

Design Patterns

Reusable solutions to common problems in software design. Explains how the elements of reusable software interact.

Classes, responsibilities, and collaborations (CRC) cards

CRC cards are a design technique for defining responsibilities, collaborations, and attributes of a class within a use case.

Deployment Diagrams

Model the implementation and describes how the software systems are deployed.
Use components and nodes to describe the systems connections (e.g. Internet server, Application Server, client computer, network computer, Database server).

Design Class Diagrams

Describes the attributes and methods for the software classes.

User Interface Design

User interface details including layouts, content, and functionality of the user application's presentation.

System Interface Design

Shows how the system interacts with other parts of the system such as the network, databases, or other external systems and specifies how they interact.

Database Design

Database schema, tables, columns, and relationships.
Database constraints like referential integrity are a part of the database design.
