Draw the ER (entity-relationship) diagram for the area you have chosen. Your ER diagram must satisfy the following constraints: 1) At least 4 entities 2) At least 1 one-to-one or one-to-exactity-one relationship (1-1 relationship) 3) At least 1 many-to-one relationship (1-to-n relationship) 4) At least 1 many-to-many relationship (n-to-n relationship) 5) If any, the appropriate one of the weak entity relationship or ISA relationship types 6) Convert the ER model you created to a Relational model. 7) Select an appropriate relation from the relational model you created and display the following prompts: 8) Identify all valid FDs (functional dependencies) for the selected relation. 9) Find the 'closure set' of the key you have determined for the selected relation (algorithm explained in the lecture) step by step with) and show that the closure set you found contains all the attributes in relation. 10) Prepare SQL DDL commands (create table) to create real database tables for each relation you created in question 6. commands will be prepared as text only.
