Step 2: Populate Relations (5) Insert the following data into the relation loan – (‘L-17’, ‘Downtown’, 1000) – (‘L-23’, ‘Redwood’, 2000) – (‘L-15’, ‘Perryridge’, 1500) – (‘L-14’, ‘Downtown’, 1500) – (‘L-93’, ‘Mianus’, 500) – (‘L-11’, ‘Round Hill’, 900) – (‘L-16’, ‘Perryridge’, 1300) – (‘L-20’, ‘North Town’, 7500) – (‘L-21’, 'Central',570)

Step 3: Retrieving Data (1) List all information stored in the database; List the names and cities of all borrowers; List the set of names and cities of customers who have a loan at Perryridge branch; List the numbers of accounts with balances between 700 and 900; List the names of customers on streets with names ending in ‘Hill’; List the names of customers with both accounts and loans at Perryridge branch;

Step 3: Retrieving Data (2) List the names of customers with an account but not a loan at Perryridge branch; List the names and cities of all borrowers; List the set of names of customers with accounts at a branch where Hayes has; List the set of names of branches whose assets are greater than the assets of some branch in Brooklyn; List the set of names of branches whose assets are greater than the assets of all branches in Brooklyn; List the names of customers with both accounts and loans at Perryridge branch (using ‘exists’)
