BITS wants to store information about the supervisors, including their supervisor number and the relationship to consultants. Supervisors can work with multiple consultants, but consultants only have one supervisor. In addition, supervisors specialize in working with clients in specific task categories. Using this information, convert the following unnormalized relation to fourth normal form:

Consultant (ConsltNum, LastName, FirstName, Street, city, zipCode, sorNum, SupervisorName) , (Tasks, Description, category, Price, SupervisorNum) )

Convert the table into normalize form

Explanation:

Un normalized relation of the given schedule is as

Consultant ( ConsultNum, Last Name, First Name, Street, City, ZipCode

HoursRate (SupervisorNum, Supervisor Num)

(Tasks, Description, Catagory, Price, SupervisorNum))

According to these functional dependencies :

SupervisorNum is dependencies of the SupervisiorNum

ConsltNum is dependencies of the Last Name, First Name, Street, City, ZipCode, Hours, Rate

Tasks are dependencies of Description, Category, Price

The consultant table is not in a normalized form as it contains repeating groups. Make composite keys such as Supervisor Num, Tasks and ConsltNum and convert the table in NF by removing repeating groups

Such as table in NF

Consultant

(Consult Num, Last Name, First Name, Street, City, Zip Code, Hours, Rate

Supervisor Num, Supervisor Name, Tasks, Description, Category, Price)
