I. Overview of the Project

The TESDA Learning Resource Center, formerly known as Information and Documentation Services (INFODOS) is currently under the supervision of the Qualifications and Standards Office.

Its main function is to support the research and training objective of the agency by providing resources and information.

Currently, it is serving policy makers, school administrators, trainers, teachers, curriculum developers, students, workers, employers and others. The number of clients served by the center has doubled yearly from its first year of operation. It started with an average of twenty (20) clients per day. Now after 5 years of operation, it is serving an average of eighty (80) clients per day.

The center is currently operating using manual recording of transaction method which results in poor services and operations for its clients. As a solution, the management decided to commission programmers to design an automated system for the center that will be used for the next five (5) years of operation.

II. Technical Specifications

A. EnvironmentThe application to be developed should be a stand-alone desktop

application and in graphical user interface (GUI) mode.

E. Transactionsa. Borrowing

The administrator will register the books borrowed by the member. There are two ways of registering the books to be borrowed: (1) through manual entry of ISBN; (2) through the reservation records of the member. The maximum number of books that can be borrowed in one transaction is based on the borrowing policy. The system should record the name of borrower, the books borrowed, ISBN, transaction number and the date borrowed.

b. Returning

The administrator needs to acknowledge the return of the books. Books from single borrowing transaction can be returned on individual returning transaction. The system should record the name of borrower, the borrowing transaction number, title of book, date the book returned and status of return transaction.Status of return transaction can be:

o Return the book without penalty (Status OK)

o Return the book with unsettled penalty

o Unreturned book without penalty

o Unreturned book with penalty

c. Reservation
