One of the properties of an IA composite primary key has a candidate key. What response would you have to this information?

What precisely does "Identifier attribute" imply when it is used?

Give an example of a primary key

A potential key exists for a composite primary key's property. How do you feel about this news?

Task Description: Consider the following relations for a company: Department (Did: integer, Dname: string, location: string) Employee (Eid: integer, Ename: string, Erank: integer, salary: real, DepartmentID, integer) Project (Pid: integer, DepartmentID: integer, Pname: string, budget: real, start year: integer) The “DepartmentID” fields in both Employee and Project are foreign keys referencing the “Did”field of the Department table.    Through Java application, use SQL to insert (random but meaningful) data records in the above tables:1) Create two different departments (named: Marketing and Human Resources)2) Create at least three employees per department (6 employees in total). A rank of an employee is an integer value between 1 and 3.3) Create at least three different projects per department (6 projects in total). The start year is between 2018 and 2020.

There is a potential key for one of the components of a composite primary key. What would be your response if you found out this?

A composite primary key possesses a candidate key attribute. What is your reaction to the aforementioned data?

3) A relation is said to be in 3NF if it is in 2NF and no nonprime attribute of R is blank the primary key. A) an alternate forB) transitively dependent on C) Part of D) partially functionally dependent onE) fully funcionally dependent on

It is possible to have both a primary key and a candidate key for the same attribute.

Assume that a main key's component attributes are likewise potential keys. How would you respond to that?
