What is the difference between a context diagram and diagram 0? Which symbol is not used in a context diagram?
What will be an ideal response?
The context diagram contains only one process symbol, process 0, which represents the entire system. Diagram 0 is a more detailed (or exploded, partitioned, or decomposed) version of process 0 on the context diagram. The major processes, data flows, and data stores for the information system are shown on diagram 0.
The data store symbol is not used in a context diagram. Use a data store only when two or more processes use that data store. Otherwise, the data store is internal to a process and not visible from the outside. Because a context diagram involves only one process, all data stores are internal to that process and do not appear in the context diagram.
