Answer the following questions: Question 1: Using your knowledge of the college environment, determine the functional dependencies that exist in the following table. After determining the functional dependencies convert this table to an equivalent collection of tables that are in third normal form. Student (StudentNum, StudentName, NumCredits, AdvisorNum,AdvisorName, DeptNum, DeptName, AdvisorNum, AdvisorName, DeptNum, DeptName, (CourseNum, Description, Term, Grade)) : Draw an ERD for the case given in Question 1.

Determine the Functional Dependencies that exist in the following Orders table. This table lists customer and order data. Orders (SupplierNum, SupplierName, Supp_Phone, ProductNum, Description, Product_type, QuotedPrice) . Normalize the above relation to 3 rd normal form, ensuring that the resulting relations are dependency-preserving and specify the primary keys in the normalized relations by underlining them.

a. Determine the functional dependencies that exist in the following table. Orders (OrderNum, OrderDate, ItemNum, Description,...

a. Determine the functional dependencies that exist in the following table. Orders (OrderNum, OrderDate, ItemNum, Description, NumOrdered, QuotedPrice) b. After determining the functional dependencies, perform 1nf, 2nf, 3nf.

Normalize the following data by: a) identifying the functional dependencies, b) stating your assumptions, \ c)...

For the relation R(A,B,C,D,E) with the following Functional Dependencies: A → B, A → C, BC → D, AC → E, CE → A, list all non-trivial FDs following from the above. Generate all possible keys for R. Check whether R is in 3NF. If it is in 3NF, explain the criteria you used. If it is not in 3NF, convert it into 3NF, showing the new relations and their FDs.
