E/R diagram: Draw a complete Doctors office system E-R diagram using UML or crow’s foot notation that includes all of the entities, attributes, identifiers. Relationships should be appropriately labeled with verb phrases. Make it neat. Once the E-R model has created, convert the E-R model to a set of relations by using rules. We will call this set of relations the initial set of relations derived from the E-R model. You use to implement your database application in MS Access....

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,...

Q1.a) Based on the business rules, you are expected to construct
an Entity-Relationship (ER) diagram. The ER diagram should include
entities, attributes (if there are less than three specified in the
business statements, please add some extra attributes), identifiers
and corresponding data types, the relationships among entities with
cardinality and associative entities.
.b) Extend Q1.a) to apply generalization/specialization
technique to construct an Enhanced-ER (EER) diagram. The EER
diagram should specify the complete (total) and disjoint
(mutuallyexclusive) constraints on the
generalization/specialization....
