Problem 5.

Choose a transaction that you are likely to encounter, perhaps ordering a cap and gown

for graduation, and develop a high-level DFD or a context diagram. Decompose this into

a level-0 diagram. For this problem, we will adopt the convention that the context diagram

has no data store. Data store(s), if needed, will be included in the level-0 diagram.

Please draw both context and Level - 0 diagrams.
