1. Introduction
1.1 Purpose
The purpose of this document is to describe the Web Library Management System (WLMS)
product with the release number 0.1. This document contains the functional and non-functional
requirements of the project. This document contains the guidelines for website developers system
engineers and designers to start working the project.
1.2 Scope
WLMS product is basically updating the manual library system into a internet-based
application so that the users can know the details of their accounts, availability of books and
remaining time for borrowing.
The project is specifically designed for the use of librarians and library users. The product will work
as a complete user interface for library management process and library usage from ordinary users.
WLMS can be used by any existing or new library to manage its books and book borrowing,
insertion and monitoring .
WLMS can work as a powerful library management system for big libraries, and can provide a free
easy-to-use system for rising libraries.
1.3 Audience Definitions, Acronyms and Abbreviations
1.3.1 Audience Definitions
The intended readers of this document are the developers of the site, testers, library owners
and managers and coordinators.
Any suggested changes on the requirements listed on this document should be included in
the last version of it so it can be a reference to developing and validating teams.
1.3.2 Acronyms and Abbreviations
Acronym Meaning
WLMS Web Library Management System
MS SQL Microsoft Structured Query Language
ASP Active Server Pages
ISBN International Standard Book Number

1.4 References
 IEEE 830-1998 standard for writing SRS document.
 I. Sommerville, Software Engineering, 8th
ed. England: Addison-Wesley, 2007.
1.5 Overview
Section 2 defines the general functions of WLMS, operating environment and user
constraints along with our assumptions.
Section 3 specifies functional and nonfunctional requirements; all of them are described to a
level of detail sufficient for designers to design a system.
Section 4 illustrates interfaces and its possible scenarios along with some screenshots to
make a general idea about the interfaces.
Section 5 specifies all stored information that we are concerned about for every entity in the
website .
2. Overall Description
2.1 Product Perspective
WLMS is a replacement for the ordinary library management systems which depend on
paper work for recording book and users’ information.
WLMS will provide an advanced book search mechanism and will make it easy to borrow,
insert and index a book in the library.
2.2 Product Functions
2.2.1 Administrators
 Admin should be able to insert, modify and delete books.
 Can accept or reject a new user according to the library policy or payment methods.
 Increase the period for borrowing a book for specific type or group of users.
 Can get the information (status report) of any member who has borrowed a book.
 Add and edit book categories and arrange books by categories.
 Add and edit authors and publishers information.
 Can send lateness warnings to people who have exceeded deadline date.
 Can record books returned by users.

2.2.2 Normal Users (Library Members)
 The member should be provided with the updated information about the books catalog.
 Members are given a provision to check their account’s information and change it.
 Members have the ability to search through books by subject, title, authors or any
information related to the book.
 Can extend the period of borrowing books according to the library policy.
 The customer may suggest a book to be brought to the library book collection.
2.3 Operating Environment
The WLMS is a website and shall operate in all famous browsers, for a model we are taking
Microsoft Internet Explorer versions 7.0, 8.0 and 9.0, with Flash Player 9 and JavaScript.
2.4 User Characteristics
Users of the website are members, librarians and the administrators who maintain the
website. Members and librarians are assumed to have basic knowledge of computers and Internet
browsing. Administrators of the system should have more knowledge of internal modules of the
system and are able to rectify small problems that may arise due to disk crashes, power failures and
other catastrophes. Friendly user interface, online help and user guide must be sufficient to educate
the users on how to use this product without any problems or difficulties.
2.5 Design and Implementation Constraints
 The information of all users, books and libraries must be stored in a database that is
accessible by the website.
 MS SQL Server will be used as SQL engine and database.
 The Online Library System is running 24 hours a day.
 Users may access WLMS from any computer that has Internet browsing capabilities and an
Internet connection.
 Users must have their correct usernames and passwords to enter into their online accounts
and do actions.
2.6 Assumptions and Dependencies
The product needs the following third party products.
 Microsoft SQL server to store the database.
 ASP.net to develop the Product.

The success of this system depends on
 Existence of an Internet service to all people in Gaza Strip.
 Are librarians and users comfortable with computers and have enough conation to work with
the product?
 Website interface must be friendly and easy-to-use.
 The search mechanism should be simple and fast.

4. Interfaces and Possible Scenarios
4.1 Login Interface
In case the user is not registered yet, he can enter the registration form after clicking on
"‫"تسجيم‬ link as shown in Figure 4.
Figure 1: Main menu
We can see " ‫تسجيم‬‫دخول‬ " pannel in the main page in
Figure 1 which asks the user to type his username and password
then click "‫."دخول‬ If the user entered either his username or
password incorrectly then an error message shown in Figure 2
will be shown.
Figure 3: Retrieve password form
Another possible scenario that an already-registered
Member has forgotten his password then he can click on " ‫فقدت‬
‫كهمة‬‫انمرور‬ " and this will lead him to password recovery page
shown in Figure 3 so he can enter his e-mail and the password
will be sent instantly to him via e-mail.
Figure 2: Login error message

4.2 Registration Interface
When the button "‫"تسجيم‬ is clicked, the server will check if the username or email is already taken
and alert the user as shown in Figure 5
If the user who is trying to register is already a member with the same username he can click
on "‫هنا‬ ‫اضغط‬ " to move to login page.
Figure 4: User registration form
After the guest reads " ‫وضوابط‬ ‫"شروط‬
and agrees it he can continue with
registration operation by entering his
name, password, e-mail, address, mobile,
telephone and personal photo.
When the user finishes entering the
required fields, he should click "‫"تسجيم‬ to
be a member of the library.
Users will be warned about any
mistakes on data format or any other
constrains by validation notes and error
messages. Figures below show some of
these mistakes with their correction
examples.
Figure 5: Server-Side Validation

There are some errors that will be shown instantly to users and do not require the server
response after "‫"تسجيم‬ is clicked. Figure 6 shows these errors.
Validation fields are used to check if passwords entered are identical and it is also used to
check if the e-mails are identical.
The Registration form also checks for the entered mobile and telephone and view an
example to help the user to enter date in the correct form.
Figure 6: Client-Side Validation

4.3 Personal Data Editing
If any member wants to change his personal information he can enter his profile by
clicking on his name at the top right of the main page and he will be directed to page shown
in Figure 7.
Member should enter his old password to verify that he owns the current account then he
can edit his personal information.
The form is similar to the registration form since same validation was used here. After the
member edits his information he should click "‫"حفظ‬ otherwise his changes will be discarded. In case
the user does not want to continue editing his information, he can click on " ‫إ‬‫نغاء‬ " button to abort the
page.
Figure 7: Personal data editing interface

4.4 Search
4.5 Advanced Search
In advanced search user can perform search operation in more specific criteria, as shown in
Figure 9, user can search by “‫انموضوع‬”“ ,‫ف‬ّ‫انمؤن‬”“ ,‫انعنوان‬” and/or other criteria. And he can select
search in “‫انكتب‬”“ ,‫انمجالت‬”“ ,‫انصحف‬”, and/or “‫األقراص‬‫انمدمجة‬” .
The user can roughly select the language of his search contents and how to display the
results by two options which are sorting the results and number of results per page.
Finally he can specify the date of the contents he wants to find by determining start and end dates.
