Recall that in Data Modeling section (Module 6, Lecture Notes of Class19.pdf) we have developed the E-R model for the Highline University database. See below for a copy of the final data model (created in MS Visio) we developed in class. After you have reviewed the E-R model, create a relational database design for the model.

  1. For each entity in the E-R model, specify a table structure, determine the data types and additional column properties, identify primary keys and foreign keys, and verify normalization on the resulting tables. Refer to the sample metadata table in Chapter 5 of the textbook for an example and use the provided metadata table template for question 1 below to format and document detailed column properties.

  2. Document referential integrity constraint enforcement actions and any business rules that you think are important. Use the provided RI table template for question 2 below to fill in as appropriate (similar to part of your team project D3 requirements). You can also refer to Chapter 5 in the textbook for an example.

Note: Use the following metadata table template for question 1 of the assignment.
