- The Database Library System is intended to Automate the library activities such as creating a new borrower, giving books to the borrowers, and maintaining the details of all the items available in the books. This also helps the librarians by providing information such as the total copies available for each book, and a list of books that belong to a particular category (Short, Long Loan, Reference items, etc.).

There are four groups of persons on whom the hospital is most dependent: employees, physicians, patients, and volunteers. Of course some common attributes are shared by all of these persons: Person_ID (identifier), Name, Address, Ciy/State/Zip, Birth_Date, and Phone. Each of the four groups of persons has at least one unique attribute of its own. Employees have a Date_Hired, Volunteers have a Skill, Physicians have a Specialty and a Pager# (pager number), and Patients have a Contact_Date (date of first contact with the hospital). Some other persons in the hospital community do not belong to one of these four groups (their numbers are relatively small). However, a particular person may belong to two (or more) of these groups at a given time (for example, Patient and Volunteer).
