Study Notes
System Development and Analysis
- SDLC stands for Systems Development Life Cycle, which is an approach to develop and maintain computer-based information systems.
- Agile methodology emphasizes flexibility and customer collaboration in the software development process.
- The primary focus of eXtreme Programming is on customer satisfaction and delivering software quickly.
- Object-oriented analysis and design provide a modular and reusable approach to software development, making it easier to maintain and modify.
System Development Phases
- The planning phase in SDLC involves identifying an organization’s total information system needs.
- The primary focus of the analysis phase in SDLC is on identifying problems and opportunities.
- The physical design phase in SDLC involves describing the system’s architecture and components.
- The implementation phase in SDLC involves translating the design into a working system.
System Development and Characteristics
- System development became more like an engineering discipline in the 1960s.
- The major breakthrough in the 1980s was the development of object-oriented analysis and design.
- System development shifted to Web application development and wireless PDAs in the 1990s.
- A System Development Methodology is a structured approach to developing and maintaining systems.
- A system has several characteristics, including components, boundaries, and interactions.
Systems Analyst and Skills
- The main responsibility of a Systems Analyst is to identify problems and opportunities and develop solutions.
- Systems Analysts require analytical skills, including problem identification, problem analyzing, and problem-solving.
- Systems Analysts also require technical skills, which need to be kept up-to-date.
- 'Systems Thinking' refers to the ability to analyze systems and identify problems and opportunities.
- Systems Analysts require interpersonal skills, including communication and collaboration.
System Concepts
- Systems Thinking involves breaking down a system into smaller components to analyze and solve problems.
- Modularization is the process of dividing a system into modules of a relatively uniform size.
- Functionality refers to the extent to which a subsystem performs a single function.
