Choose an organization that you interact with regularly. List as many different "systems" (computer-based) as you can that are used to process transactions, provide information to managers and executives, help managers and executives make decisions, aid group decision making, capture knowledge and provide expertise, help design products and/or facilities, and assist people in communicating with each other.
(1) Draw a use case model diagram ensuring that you provide the appropriate use case symbols for actors; clearly show the relationships between the actors for 4 different processes.
(2) Draw a simple process model/DFD that depicts the existing processes in the system, along with their inputs, outputs, and data. The DFD must show the flow of data between and through processes, and must also show the places where data is stored.
(3) Draw a simple data model/Entity Relationship Diagram (E-RD).
After drawing the above diagrams, do you believe that these systems are well integrated?
