1. Obviously, conceptual data modeling is a time-consuming and expensive process. Discuss the potential drawbacks to skipping this process and moving right into physical database design.
2. Produce a list of five potential entities that would need to be represented when building a conceptual data model for an academic program in a university. Provide a justification for why each proposed entity is a legitimate entity in this context.
3. Identify and discuss the advantages potentially provided by creating an entity-relationship data model to support structuring data requirements in systems analysis.
4. Identify and explain the unique capabilities of class diagrams compared with E-R diagrams for modeling data.
5. Relate data modeling to process and logic modeling as different views of describing an information system.
