Study Notes
Software Fundamentals
- Software is a collection of codes that perform specific tasks.
- Engineering is applying scientific knowledge to design, build, and improve processes.
- Software includes programs and documentation (manuals, procedures).
- Software is broader than a program, encompassing all supporting data and configuration for correct operation.
Software Components
- Programs are the core software applications that execute tasks.
- Software documentation explains how to operate, maintain, and use the software.
- Manuals provide user guides.
- Operating procedures outline the steps to run the software.
- System documentation describes software structure and architecture.
Software Categorization
- Application software helps users with specific tasks (word processing, image editing).
- Examples: Microsoft Office, Adobe Photoshop.
- System software manages and controls hardware.
- Examples: Operating systems (Windows, Linux), device drivers.
- Computer programming tools support software development and maintenance.
- Examples: Antivirus, firewalls, compilers, linkers.
Software Classification by Type
- Customized (bespoke) software is designed for one client with specific requirements.
- Example: Custom software for a library.
- Generic software is created for multiple users by a development organization and sold to customers.
- Examples: Microsoft Word, Adobe software.
Software Attributes
- Maintainability ensures the software adapts to changes and future needs.
- Dependability involves reliable and trustworthy services.
- Reliability means consistent and accurate functionality.
- Security involves protection against unauthorized access and threats.
- Safety prevents harm from system failures.
- Efficiency minimizes wasted effort during development.
- Market Availability describes the software's purchasing and use by everyone.
- Software must be understandable, usable, and compatible with existing systems.
Software Development Lifecycle (SDLC)
- Software development models define stages, sequences, and processes for software creation.
- Waterfall model: A sequential approach with stages (analysis, design, development, testing).
- Iterative Model: A repeated approach in which stages are done repeatedly.
- Prototyping model: A customer-centric approach that involves creating a model of a product that works.
- Spiral Model: A risk-driven process that combines elements of several models.
- V-Shaped Model: A testing-driven approach that involves testing each stage backward.
- Big Bang Model: A simple model implemented with little planning.
- Agile Model: An iterative approach focusing on customer feedback.
Agile
- Agile Methodology is an approach that uses continuous cycles, collaboration, and flexibility.
- Iterative development with continuous improvement using customer feedback.
- Key Frameworks: Scrum, Kanban, XP, among others.
Software Requirements
- Software Requirements Specification (SRS) defines software purposes and environments.
- Types of Software Requirements include:
- Functional Requirements: describe what the software does.
- Non-functional Requirements: address quality attributes like performance and security.
- Collection methods: interviews, focus groups, workshops, questionnaires, observations etc.
- IDEF models are graphic models for functional, data, and dynamic software design.
Software Requirements Gathering
- Methods such as interviews, focus groups, questionnaires, and surveys to gather information for requirements.
- Formats: Natural language documents, graphic models (IDEFO, IDEF3, DFD, UML), and formal specifications (SRS).
