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.

A well-structured database starts from an effective Entity Relationship Diagram (ERD). For this part of the question, you will need to sketch an ERD for the following gym scenario: A member must have a member ID, name and contact number, can be enrolled in one or more gym session. A gym session can be enrolled in by one or more members. Each gym session is identified by a session ID, and has a name, date and instructor details (Instructor ID). An instructor has an instructor ID, name and contact number, and must only be assigned to one gym session. A gym session can have one or more instructors assigned in it.” *show entities, relationship types and cardinalities. Crow’s foot model notations recommended.

San Diego Hospital Example ERD Problem Entity Relationship Diagramming is a "top down" user process. Take the following user provided information and draw the appropriate ERD. Follow the Simple Procedure for ERD diagramming to design an ERD using the following user provided information. Remember the ERD will eventually turn into the design for a database from a top down view. Make sure you resolve any many to many conflicts. Label an identifier or primary key and all pertinent attributes given. If an attribute is not readily apparent from the user information, then make one up that makes sense for the particular entity. Therefore, all entities should end up with at least an identifier and another attribute that makes sense. Please use a drawing tool of some type to show the ERD diagram (Word, PowerPoint, and Visio all work well). I want you to get in the habit of drawing these with a computer instead of by hand, as this will be important as we get to more difficult…
