This particular transaction was chosen because it is a common and familiar process that many students go through as they near the end of their academic journey. By examining the data flow for this transaction, we can gain insights into the various components and processes involved in completing such a transaction.
A context diagram or a high-level data flow diagram (DFD) can be effectively used to represent the data flow for the transaction of ordering a cap and gown for graduation. This diagram will outline the main entities involved in the transaction, as well as the flow of data between them.
The data flow for this transaction can be divided into four main components:

They provide various details such as their name, student ID, height, and weight that are essential for ordering the correct size of the cap and gown. The student also selects the desired color and style preferences for the cap and gown.
2. University Bookstore: The university bookstore is responsible for fulfilling the order and providing the cap and gown to the student. They receive the order details from the student and process the payment. Once the payment is confirmed, the university bookstore prepares the cap and gown according to the student’s specifications.
3. Manufacturer: The manufacturer is responsible for the production and supply of the cap and gown. They receive the order information from the university bookstore and manufacture the cap and gown based on the provided specifications.
