Primary Assignment.
- Look at problem #1 posted in the file ER_Questions.pdf. The problem describes a business situation.
- Your assignment is to create a high-level data model. By high-level data model, I mean model the entities and their associations and cardinality. No not model the attributes or domains.
- Create the data models in PowerPoint or PDF. List all assumptions with each model.
- Hint: Not all objects in the business description need to be modeled. Part of being a good data modeler is to select those entities necessary to build an information system to support the business situation, not to model everything. Your first task in developing a data model is to list the entities of interest.
