Part 2. Task Assignment Database

2. See Q20 in pages 210 of the textbook.

2A. Draw an initial ERD based on the initial requirements.

2B. Draw an revised ERD for the new requirements.

Note: A list of design decisions for each ERD is NOT required. Just draw the initial and the revised ERDs.

Note: The ERD must include not only entities and relationships with cardinalities but also all attributes. Every entity must have a designated primary key. There must be no many-to-many relationships and no multi-valued attributes. Enter all foreign keys in the ERD.

2C. Convert the revised ERD into a relational mode.

Note: You do NOT need to convert the initial ERD. Just convert the revised ERD.

Note: A relational model is a collection of table specifications that include table names, column names, primary keys, and foreign keys. See Page 2 of Chapter 6 Slide file for the detail.

Note: Examples of relational models converted from ERDs are in Pages 1833 of Chapter 6 Slide file.
