Exploring Data and System Development
What are data-flows and processes in an information system?
What is the Systems Development Life Cycle (SDLC)?
What happens during the requirements identification stage of the SDLC?
What is the purpose of the design stage in the SDLC?
What activities occur during the implementation stage of the SDLC?
Answers and Descriptions:
Answer: Data-flows represent the movement of data between components of an information system, while processes are the actions or transformations applied to the data to produce outputs.
Description: This question helps students understand the dynamic nature of information systems, focusing on how data is manipulated to generate useful information.

Description: This question introduces the SDLC, providing a framework for students to understand the systematic approach to system development.
Image: [Placeholder: Circular diagram of SDLC stages]Answer: During requirements identification, stakeholders’ needs and system objectives are gathered and documented to define what the system should do.
Description: This question emphasizes the importance of understanding user needs as the foundation for system development, a critical first step in SDLC.

Description: This question helps students understand how planning translates into technical specifications, bridging the gap between requirements and implementation.

Description: This question focuses on the practical development phase, helping students connect theoretical design to actual system creation.
