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 m anual 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 fi ve (5) years of operation.

Technical Specifications Environment The application to be developed should be a stand-alone desktop application and in graphical user interface (GUI) mode.

Book information panel (1) – This shows detailed information about a particular book in the collection. Navigation button (2) - There should be a navigation control that allows user to browse through the collection. Filter panel (3) – This input interface allows user to narrow down the book collection by providing the specific book category and key words from the book title and author. When ISBN entry has been provided, the search filter will focus only on the ISBN entry. Button (4) – This button is inactive while the user is not logged into the system. Details of this button are described under the reservation facility. Log in button (5) – This is the button that calls the log in interface of the system. “Search and Reserve” and Transaction Tab Control (6) – This allows allows user user to switch between the two panels however the transaction panel is not yet enabled at this stage.

2. Log Log in in Fac Facil ilit ity y a. Features

This facility should have the following features: •

The interface interface should accept only the the following following inputs: inputs: o Username o Password o Execute command o Cancel command

•

Log in/Log out button (1) – Initially the text in this button indicates “Log in”. This is used to call and show the log in panel. Once the user successfully logged in to the system, the text in this button will indicate log out. This button is now used to log out a user to the system. Log in panel (2) – This interface is where the user inputs the user account and executes the user validation process of the system (checking of authenticity of the user account and validity of membership). After the process it should render the following output: o Message box indicating the message “Welcome ” for valid user account o Message box indicating the message “Sorry invalid username or password” for invalid account entry. o Message box indicating “Sorry your account is currently inactive. Please update your membership account before you can continue.” Account information (3) – This indicates the first name and role of the logged user. It displays “Welcome Guest” with no user role if the current user has not logged into the system. Members Panel (4) – This is the same form with the guest panel. The difference is that there are elements of the form that is active once the member logs in. Administrator Panel (5) – This form is called and displayed when an administrator logs into the system. Elements of this panel is described under the borrow transaction facility.

Transactions a. 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. Retu eturnin rning g

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. Rese eserva rvatio tion

The member can reserve the title of the book to be borrowed. The reservation policy should be strictly followed in this function. The system should record the name of borrower, the books borrowed, ISBN, transaction number and the date reserved
