Given this discussion we may present problem 1s

This preview shows page 2 - 4 out of 9 pages.

Given this discussion, we may present problem 1's solution this way: __7__ Normalize the conceptual model. __3__ Obtain a general description of company operations. __9__ Load the database. __4__ Create a description of each system process. _11__ Test the system. __6__ Draw a data flow diagram and system flow charts. __5__ Create a conceptual model, using E-R diagrams. _10__ Create the application programs. __2__ Interview the mechanics. __8__ Create the file (table) structures. __1__ Interview the shop manager. b. Describe the different modules that you believe the system should include. Again, this question may be addressed in several ways. We suggest the following approach to develop a system composed of four main modules: Inventory, Payroll, Work order, and Customer.
We have illustrated the Information System's main modules in Figure P6.1B. Figure P6.1B The ABC Company’s IS System Modules The Inventory module will include the Parts and Purchasing sub-modules. The Payroll Module will handle all employee and payroll information. The Work order module keeps track of the car maintenance history and all work orders for maintenance done on a car. The Customer module keeps track of the billing of the work orders to the customers and of the payments received from those customers. c. How will a data dictionary help you to develop the system? Give examples.
d. What general (system) recommendations might you make to the general manager? (For example, if the system will be integrated, what modules will be integrated? What benefits would be derived from such an integrated system? A nd so on.)
