What are the four steps in transforming anE-R diagram into normalized relations?
Transform the E-R diagram of Figure 7-20 from the textbook into a set of 3NF relations. Make up a primary key and one or more non-keys for each entity that does not already have them listed.
Can you please help me in how I can turn the Entity Relationship diagram into a Logical Database Diagram?
I know I need to list out all the entities, but I am not sure how to draw the relation. If you would please write it step by step for me so I can practice, that would be much appreciated.
