- What is the most common method of specifying a primary key in a relational schema description?

The product table will have two attributes; product ID as integer, not null, and a primary key constraint set to unique. product description as varchar(30), not null specification. I am not sure how to do a primary key contraint set to unique. I believe I did the first two correct.arrow_forwardUsing the STUDENT table structure in picture, do the following: 1. Write the relational schema, draw its dependency diagram and identify all dependencies, including all partial and transitive dependencies. You can assume that the table does not contain repeating groups and that any invoice number may reference more than one product. (Hint: This table uses a composite primary key.) 2. Remove all partial dependencies, write the relational schema, and draw the new dependency diagrams. Identify the normal forms for each table structure you created. 3. Remove all transitive dependencies, write the relational schema, and draw the new dependency diagrams. Also identify the normal forms for each table structure you created. 4.
