PRACTICE DATABASE DESIGN PROBLEM

Imagine that your town library wants to keep track of its business in a database, and that you have been callec in to build the database. You talk to the town librarian, review the old paper$-$based records, and watch people use the library for a few days. You learn the following about the library:

Any resident of the town can get a library card simply by asking for one. The library considers each cardholder a member of the library.

The librarian wants to be able to contact members by telephone and by email. She calls members when books are overdue or when requested materials become available. She likes to email a thank$-$you note to each patron on his or her anniversary of becoming a member of the library. Without a database, contacting members efficiently can be difficult; for example, multiple members can have the same name. Also, a parent and a child might have the same first and last name, live at the same address, and share a phone.
