In summary, create a Word document for your design which includes:
- Three entities and each entity should have at least three attributes.
- Properly Identify all Primary (Use Solid Underlines) and Foreign Keys (Use Dotted Underlines)
- Define the relationships between entities (See examples in Data Model and Database Entities and Relationship Modeling lessons)
- Create an entity-relationship diagram (ERD) from the entities. You may use SmartDraw, Visio, Erwin, or even PowerPoint or Word to draw the diagram. Take a screenshot (no need if you use Word) and insert it into the Word document.
