The output of system design stage is represented by
A. State diagram
B. Structure chart
C. ER diagram
D. Context diagram
Answer: Structure chart
The system design stage is where requirements are translated into a blueprint for the system. It’s where the planning and design leads to building the product which finally moves to the testing phase. The output of the system design stage is represented by Structure chart, Data Flow Diagram and Entity Relationship Diagram.
Structure charts show how a software module or group of modules are structured together and how each module interacts with other modules. They provide information about what functionality each module performs and specify how this functionality will be achieved. As a result, structure charts are used to describe logical structures and indicate hierarchical levels in systems. Each box in a structure chart represents a process, which is any action that is performed by the system.
Data Flow Diagrams:
A data flow diagram (DFD) is a graphical representation of the “flow” of data through an information system, modeling its process aspects, it also called as a bubble chart. Often they are a preliminary step used to create an overview of the system without going into great detail, which can later be elaborated. DFDs can also be used for the visualization of data processing (structured design).
