The following are the main entity types of the academic institution database. For each entity type, we provide some of the corresponding attributes. Use this information in order to: (a) Build an Enhanced E-R diagram; (b) Transform the Enhanced E-R diagram to a relational database. Identify the primary key(s) and the foreign key(s) for each relation. Draw the relational integrality constraints; (c) For each of the relations created, indicate its normal form. If the relation is not in the 3NF,...

In this phase of the project you will create an ERD based upon the following requirements and business rules. Limit your ERD to entities and relationships based on the business rules showed here. In other words, do not add realism to your design by expanding or refining the business rules. However, make sure you include all attributes needed that would permit the model to be successfully implemented, including all primary and foreign keys. 1. Trinity College (TC) is divided into...
