Question 2 Consider the Library Database consisting of four relations. The library has many branches. Copies of the same book can be placed in different branches. BOOKS (book id, title) AUTHORS (book id, name) BOOK_COPIES (book id, branch id) LIBRARY BRANCH (branch id, name, address) AUTHORS (book_id) is a foreign key to BOOKS. BOOK_COPIES (book_id) is a foreign key to BOOKS. BOOK_COPIES (branch id) is a foreign key to LIBRARY_BRANCH. Translate each of the following queries on this schema to SQL. 1. 2. Retrieve a list of book titles along with library branches they are in Retrieve list of book titles that are available in all branches of the library.

The database used for this question is a very simple one with the following schema: (Primary keys are bold, foreign keys are underlined) CUSTOMER (CustID, FirstName, LastName, City, Phone, Email) INVOICE (InvoiceNumber, CustID, Date) INVOICE_ITEM(InvoiceNumber, ItemNumber, Quantity) ITEM (ItemNumber, ItemName, UnitPrice) When a customer makes a purchase, an invoice is created. The invoice may be for many items. For example, in a single purchase, a customer might buy 10 Back Scratchers, 4 Hair Removers and a Dog Lead. Provide relational algebra (NOT SQL) queries to find the following information. NOTE: You can use the symbols s, P, etc., or the words’ PROJECT’, ‘RESTRICT’ etc. as you prefer. You do not need to try to make efficient queries – just correct ones. Where you use a join, always show the join condition. List the dates on which Homer Griffin made purchases.
