Construct a Context as well as Level 0 Data Flow Diagram (DFD) of any DVD rental System. Guidelines / Requirements: The context level diagram must contain a major process and external entities. Level 0 diagram must consist of major functions and should work as follows: There should be 2 streams, or flows of data. · The customer request to rent a DVD, system check the availability from DVD store, and then system get the details of customer · Bill will be generated on behalf of the detail of DVD and handed over to customer. And finally customer gets the DVD after payment in cash. Purposes: Ensure that you can analyze existing manual system and can draw Data Flow Diagrams of any proposed system. Before Starting you should study and understand: Rules for drawing DFDs. Differentiate different levels of DFDs.
