Study Notes
Software Development Process
- Software is a collection of computer programs, procedures, rules, associated documents, and concerned data for operating data processing systems. It also includes pictorial, video, and audio representations.
- Software is categorized into system software and application software.
- System software controls and integrates hardware components like monitors, printers, and storage devices. Operating systems are an example.
- Application software performs specific tasks, such as word processing or reservation systems. Microsoft Office applications are examples
- Software characteristics determine its quality. Good software is understandable, cost-effective, maintainable, and reliable. Modularity helps in testing; functionality addresses user requirements, reliability means consistent service, portability ensures adaptability in different environments, and correctness aligns with requirements. Documentation and reusability are also important aspects.
Software Characteristics
- Software characteristics decide on the software's quality. Attributes reflect the product quality, dependent on the application.
- Example qualities include understandability (ease for users), maintainability (ease of modification), cost-effectiveness, and reliability.
Software Doesn't Wear Out
- Software's failure rate, represented by a "bath-tub curve," initially high, drops to a steady state, and then increases again due to hardware factors like vibration, temperature extremes, and dust.
- Software doesn't wear out; it's not affected by environmental factors like hardware, instead its initial failure rate is high due to errors, but becomes reliable over time.
Software Engineering
- Software engineering applies a systematic, disciplined, and quantifiable approach to software development, operation, and maintenance.
- Software engineering is a layered technology, including process, methods, and tools to enable timely product development.
Generic Software Engineering Activities
- A framework provides a standard to build software.
- The process involves framework activities which usually apply to all projects, plus umbrella activities (non-SDLC activities) for all projects.
- Communication between customer and developer is the start of the process of software development.
Software Development Processes
- Planning: This phase involves defining goals, estimations (schedule, cost), project development, and tracking.
- Modeling: Modeling phase involves a detailed requirement analysis and the design of the project. (algorithms, flowcharts).
- Construction: The construction phase deals with generating codes according to specifications and programming languages, creating testing scripts to confirm code produces correct outputs.
- Deployment: The deployment of the final product follows, which entails transferring it to the client.
Software Development Models
- Waterfall: This model is sequential with distinct phases of requirements, design, implementation, testing, and deployment.
- Iterative/Waterfall: A more practical version where each step incorporates feedback and potential corrections are implemented using successive versions.
- Incremental: This model builds and delivers parts of the software progressively in successive increments.
- Spiral: Emphasizes on risk assessment and iterative development, potentially involving prototypes, and reviews at each step until the end product is delivered.
- RAD (Rapid Application Development): Aims for quicker deliveries, relying heavily on reusable components and rapid development cycles that allow for user feedback during development.
- Prototyping: Building a working version or model of the software which allows users to provide feedback for further enhancements.
- Agile: Agile methodology (a family of development methodologies) is very flexible, allows for changes depending on the requirements and feedback received during the development.
