- What are the characteristics of a strong entity set as opposed to a poor one?When is it necessary to represent a many-to-many connection using an associated entity?Direct connections between external entities and the database are not permitted under any circumstances. It should be kept in mind as one of the data flow diagram design concepts to consider. What do you think the repercussions of this suggestion will be?
- 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.

- When working with database entity relationship modeling, should the cardinality between entities be translated/ read from both ends of the notation? In other words, should a relationship between entities have the ability to understood if read forwards and backwards?What are the rules for choosing how to recognize and create connections between entities in the ER-Model?Build an entity-relationship diagram, deriving relations and validating relations using normalization up to third normal form
