Question 2

ii) Identify the repeating group of attributes and transform part  (i) into tables that are in 1st Normal form. (Explain the rationale for your decision).

iii) Identify any partial dependencies in part (ii) and transform them into tables that are in 2 nds Normal Form. (Explain the rationale for your decision).

iv) Identify any transitive dependencies in part (iii) and transform them into tables that are in 3rdNormal Form. (Explain the rationale for your decision).

Part B:  (Please clearly state all assumptions and ensure that you have included the screen capture for each part – marks will be deducted if you do not provide evidence of execution) Using any dialect of SQL, please complete the following SEVEN (7) parts:
i) Draw an entity-relationship diagram of the identified tables in Part A.

ii) Using the CREATE TABLE in any dialect of SQL, show the corresponding SQL tables. Indicate the primary key, foreign keys, column names, constraints, etc.

iii) Insert (at least) 10 sample rows for each identified table.

iv) List the names and phone numbers of all customers who have a credit limit > $10,000 in alphabetical order.
