Requirements for Database Design

Database Design Requirements1. To determine the data requirements, Read the case study:

Steps to Design and Build Database

1. Identify the Tables required2. Identify the relationship between Table based on the logic

in the case3. Create and draw the Entity-Relationship Diagram

• Remember Table is referred to an Entity in the diagram, So Table = Entity• Remember to resolve many to many relationships with a link table

4. Determine the attributes/fields for each entity/table5. Build Database in MS Access

• Microsoft Access Video Training

• Initial ERD- with many to many

• Final ERD- many to many resolved
