Also keep in mind what your team has accomplished in your system development work to this point. At this point, your team has designed and implemented an information requirements determination process and has completed tasks related to discovering and diagramming system processes through data flow and use case diagramming. Now it is time to complete an essential first step in structuring system data requirements.
Your team has determined that a relational database system will be used to support the company's inventory management processes. The database design process involves three stages:
Following the third stage, the physical data design will be implemented in a commercial relational database product. The deliverable from the logical data design could be implemented in any relational database product, so you are not concerned with physical implementation issue for a specific product until you reach the physical data design stage.
The Tasks:
This task involves the development of components of a conceptual and logical data models, as described in Chapters 8 and 9, for the business. The work for Tasks 1, 2, and 3 is to be completed in a single Word document with the deliverables of each of the three subtasks clearly labeledas Task 1, Task 2, and Task 3.
