May I ask for part (iii), user -> nonregistered and user -> registered is in which NF? it wasn't clear. The follow up answer was for a different question.

Please help me with this question ERD diagram.

Create an order for the generic definitions by making use of the main key definitions from the 2NF and 3NF. Provide a comprehensive example to prove your assertion.

Suppose you were asked to define a class MetaDisplay in Java, containing amethod static void printTable(String r); the method takes a relation name r asinput, executes the query “select * from r”, and prints the result out in tabularformat, with the attribute names displayed in the header of the table. What JDBC methods(s) can get you the required information?t?

Calculate the following transitive closures

Define metastability.

2NF and 3NF are defined differently by the main key definitions than they are by the generic definitions. Give a specific example to support your claim.
