Study Notes
Chapter 12: Construction
- The Systems Development Life Cycle (SDLC) has phases: Idea, Planning, Drawing Analysis, Blueprint Development, and Construction Implementation.
- The Construction phase focuses on building the system, including programming, testing, and documentation.
- Documentation is crucial for usability and maintenance. Types include system documentation (for developers/analysts) and user documentation (for end-users).
- System documentation includes reference materials, procedural manuals, and tutorials and is largely a byproduct of the analysis and design process.
- User documentation guides users on system operations, including reference documents for tasks, procedures manuals for broader processes, and tutorials for learning fundamental system aspects.
- The diagrams show how documentation is structured, highlighting topics, tasks, navigation controls, and other components.
- Testing in systems development is vital. Key test types include unit, integration, system, acceptance (alpha and beta).
Construction Phase
- Testing and documentation are crucial, often taking more time than programming.
- Efficient programming relies on careful module assignment, robust coordination, and schedule management.
- Analysts are involved in oversight, testing, and coordinating the development process.
Programming Management
- Systems analysts play a key role in the oversight, testing, and coordination of the development process.
- Efficient programming depends on careful module assignments, robust coordination, and schedule management.
- Documentation is categorized into system documentation (for developers/analysts) and user documentation (for end-users).
- Good documentation is essential for system usability and maintenance. This includes reference materials, procedures manuals, and tutorials.
- Testing in system development ensures the system works as intended, meeting functional and non-functional needs (like security and performance). Test types include unit, integration, system, and acceptance tests.
Testing in Systems Development
-
Testing's purpose is to identify discrepancies between expected and actual system behavior.
-
Focus is on early error detection to save costs and enhance quality.
-
Testing kinds:
- Unit testing: Tests individual components (classes, methods)
- Integration testing: Ensures modules work together focusing on data flows and interactions.
- System testing: Examines the entire system's ability to meet functional and non-functional requirements.
- Acceptance testing: End-users verify system meets needs (alpha and beta testing). Alpha testing uses test data, beta testing uses real-world data for close observation.
