Enhanced ER Model

The enhanced ER model is an abbreviation for Enhanced Entity-Relationship (EER) model. As you know, the entity-relationship (ER) model is a pictorial illustration of the relationship between various entities of a domain. In the case of a large amount of data with multiple interrelated entities, the ER diagrams become complex and tough to interpret. For such cases, the need for enhancement in the ER model was observed, and thus, the EER model was designed.

I want to create logical database design: 1. Normalize the relations to at least third normal form (3NF) using proper standard E-R diagram notation. Provide the appropriate relational schema reduction. 2. Identify the primary and foreign keys for each relation (using appropriate notation). Maybe either list the primary and foreign keys or generate a schema diagram??? 3. Identify and describe any indexes needed to speed up searches on non-key attributes – can you explain it too? So I would understand why you come up with the answer please? 4. Identify and describe unique, conditional (check), non-null, referential integrity, or other constraints needed to guarantee the integrity of the database. 5. Describe the set of business or workflow rules applicable to your project. Next, describe at what point in the workflow you will implement the business or workflow logic and the justification for doing so.Below are my conceptual design.
(ii) Four entities of the organization are: Worker, Customer, Product and Department. (a) Suggest an identifier, with justification, for any three entities.

For example STUDENT( StedentMaricule, name, gender, DOB) for the entity student.
