1. Project Drivers
1.1 Purpose
The purpose of this document is to familiarize reader with software, which is developed by
Dream Team Corporation. Specification describes all hardware and software requirements
for product, behavior of it and its components. Software Requirements Specification (SRS)
allows to verify the customer that all his requirements are observed and implemented
correctly by developer.
The intended audience for the SRS reading consists of system end-users (patrons),
customer engineers, software developers (defined by Ian Sommerville for system
requirements)[1].
1.2 Scope
The Dream Team Corporation was invited to develop College Library Management System
for National Innovation Foundation (N.I.F). The software will reflect all the requirements
defined by the customer.
College Library Management System will allow to perform all necessary procedures for
librarians and patrons. According to customer requirements the software to be developed will
consist of three databases:
 Item’s database (books, journals, magazines, newspapers, diploma thesis, etc)
 Patron’s database
 a small Access-based database with information about digital items, that College has
(software, music) integrated with Item’s database
LMS will also provide all necessary services for databases such as creating, deleting,
updating and searching information. Patrons will be able to access to the library site (webbased) through the Internet or through the library’s LAN-connected computers, scattered
throughout the library for sending request, receiving information about current status of the
books or renewing them. The design of product interface to be developed will be supported
by Microsoft IE, Netscape Navigator and Opera browsers.
User interfaces will be
ergonomical and easy-to-use.

1.5.2 Viewpoints
This project consists of several stakeholders, which were defined above. According to Ian
Sommerville’s article ‘Viewpoints for requirements elicitation: a practical approach’ [2]
software requirements can be described by using PREview model. The viewpoint model is
deliberately flexible and informal. Viewpoints can be adapted to specific organizational
practice and standards as can the notations used to describe system requirements.
7
The Dream Team Corporation, Requirements Specification v1.1
010752000 Team project, Project-Based Software Engineering
08.03.2016
Viewpoints may be used during the early stages of a requirements engineering process as a
structuring mechanism for requirements elicitation and analysis. Identifying viewpoints and
organizing information around them at this stage reduces the possibility that critical
information will be missed during requirements elicitation and provides a traceability
mechanism for linking requirements with their sources. Let us define the following model of
stating a viewpoint PREview:
The viewpoint name.
The viewpoint focus.
The viewpoint concerns.
The viewpoint sources.
The viewpoint requirements.

Database. Database is intended for storing different types of data such as users,
books etc.
SQL server. This server is intended for Database management. It receives
commands from Library System Engine and according its demanding take data from
database.
Library System Engine (LSE). This is the core of LMS system. It is intended for
processing of client’s inquires and has standard library of functions. By means of this
functions LSE connects to database server (SQL server) and generate requests for data
issue, data renew, deleting data, etc from database. Requests are made on standard
language named Structured Query Language (SQL). LSE can be implemented by different
ways. In this LMS system it will be implemented in Java.
As it’s shown at Fig. 2, LSE consist of several modules (every module response for
certain operation): authorization module, search module, e-mail module (intended for e-mail
distribution) and others.

User Interface Engine (UIE). UIE allows to work with LMS system by means of Webbrowser (through the web). It can be implemented in PHP script language for connection
between server database and user web interface. UIE interacts with LSE by means of byte
stream protocol. This protocol allows to provide interaction between programs realizing user
interface (Web or Windows) and core of LMS. Byte stream protocol consist from set of
13

messages of certain types such as request for registration, registration’s result, request for
search, result of search and others.
2.2.2 User Interface
The LMS is designed for using by two main classes of users: librarians and patrons.
If according to log data user have “user” status then after logon he/she will see main window
showed on the Figure 3.
Main user’s menu consists:

Users Info: here user can find his personal data (fig.5);

Account: information about loans (fig.6);

Search: provide detailed search through the library (fig. 7);

Password: this function intended for changing user’s password;

Home: return user to main window (fig.4);

Log Out: this function is intended for exit from user’s settings.
Fig. 3 User Interface
As for librarians, they have similar interface, but some control features are added. If
according to log data user have “user” status then after logon he/she will see main window
showed on the figure 4.

3. FUNCTIONAL REQUIREMENTS
3.1 The Scope of the Work
At the beginning of October 2002 the Dream Team Corporation was represented a task to
develop a College Library Management System by National Innovation Foundation (N.I.F).
Software to be developed should be provide all necessary action for library staff and patrons.
There are several motivations to order new computer-based College LMS:
1. To modernize College Library database, where data was stored in a card-based
catalog
2. To optimize librarians’ work and time
3. To join small Access-based database, where library has stored information about
digital items (software, music)
