Database Management Systems

This one question 4 part. Please give all necessary things. Thanks

What to submit:

Submit SQL commands used to answer Part 1, Part 2, and Part 3. Make sure that your SQL script runs without any errors. Submit screen shots of running commands for Part 2. Submit answers to Part 4 along with explanation of the system response to your command (so in case of error, explain why the error happened, in case the insert works, explain why it worked).

Part 1 (3 Points): Creating the database:

Create the following tables. The underlined bold column names are the primary keys. Make sure to specify the primary and foreign key constraints in your create table statements.

1. Branch(branch_id:integer, branch_name:varchar(50), branch_city:varchar(50), assets:numeric(11,2)

2. Loan(loan_number:integer, branch_id:integer, amount:numeric(8,2))

foreign key branch_id references Branch(branch_id)

3. Customer(customer_id:integer, customer_name:varchar(30), customer_street:varchar(30), customer_city:varchar(50))

4. Borrower(customer_id:integer, loan_number:integer)

foreign key (customer_id) references Customer(customer_id)

foreign key (loan_number) references Loan(loan_number)

5. Depositor(customer_id:integer, account_number:integer)

foreign key (customer_id) references Customer(customer_id)

foreign key (account_number) references Account(account_number)

6. Account(account_number:integer, branch_id:integer, balance:numeric(8,2))

foreign key branch_id references Branch(branch_id)
