REQUIREMENT SPECIFICATION AND DESIGN

A] Technology Used- Visual Studio.NET:

As per our literature survey and requirement analysis, weve seen that .NET Platform canbe considered as most efficient platform choice for our system development, because of reasons

stated as below:

VB.NET is most widely used in such commercial application development.

Microsoft Visual Studio.NET Provides RAD (Rapid Application Development) support,

which may enhance our application development speed.

Besides above advantages, .NET may also help to solve development issues, providing

features as listed below:

Simpler, Faster development

Automatic handling of system-level tasks such as memory management and process

communication. Excellent tool support.

Although much of what the CLR does is similar to operating system

functionality, it is very much designed to support development languages.It furnishes a rich set of object models that are useful to tools like

designers, wizards, debuggers, and profilers, and since the object models

are the runtime-level, such tools can be designed to work with all .NETLanguages.

Simpler, safe deployment.

Applications produced in the .NET Framework can be designed to install

with a simple XCOPY command i.e., applications just needed to be copiedand pasted. Above procedures assumes that appropriate version of .NET

Framework is installed in target system.

.NET Class Framework:

The .NET Class Framework contains literally thousands of classes and Interfaces. Here are

just some of the functions of various libraries in the .NET Class Framework.

Data access and manipulation.

Creation and management of threads of execution.

Interfaces from .NET to outside world- Windows Forms, Web Forms, Web Services, andconsole applications.

Definition, management, and enforcement of application security. Encryption, disk files I/O, network I/O, serialization of objects, and other system-level

functions.

Application configuration.

Working with directory services, event logs, performance counters, message queues, and

timers.

Sending and receiving data with a variety of network protocols.

Accessing metadata information stored in assemblies.

B] Microsoft SQL server:

Microsoft SQL Server is a relational database-management system that scales from

laptops and desktops to enterprise server. SQL server was originally developed in the 1980s atSybase for UNIX system and later ported to Windows NT Systems by Microsoft. The latest

release, DQL Server 2005, is available in express, standard, and enterprise editions and localizedfor many languages around the world. SQL server refers to all of these editions of SQL Server2005.

SQL Server provides many Management, Design and Querying Tools, most of these toolscenter around the SQL Server Management Studio (formally known as Enterprise Manager). The

Management Studio provides a common shell for administering all services associated with SQL

Server, which includes Database Engine, Analysis services, Report generating services, SQLServer Mobile, and Integration Service.

Some of these tools include:

Query Editor

o The integrated Query Editor provides a simple graphical user interface for

running SQL queries and viewing the results.

SQL Profiler.

o SQL Profiler is a graphical utility that allows database administrators to monitor

and record database activity of the SQL Server Database Engine and Analysis

Services. It can display all server activity in real time.

The Database Tuning Advisor.

o Queries and updates can often execute much faster if an appropriate set of indices

is available. Designing the best possible indices for the tables in a large database

is a complex task.

SQL Management Studio.o SQL Server Management studio supports centralized management of all aspects

of multiple installations of the SQL Server Database Engine, Analysis Services,

Reporting Services, Integtration Services, and SQL Server Mobile. It allows

support for data administration.

Hardware And Software Requirement Specification:

B] Hardware Requirement Specification:

The system utilizes client server architecture, so the hardware requirement for system, inorder to operate properly, can be classified as-

A] Server Requirements:

1] CPU:- AMD/Intel i386 compatible processors above 3GHz speed.

2] RAM:-Above 2GB.3] Free HDD Space: - 10 GB or more. (RAID System can also be used).

(Recommended Machine: IBM Server Edition 4.0)

B] Client Requirements:

1] CPU: AMD/Intel i386 compatible processors above 1 GHz speed.2] RAM: Above 512 MB.

3] Free HDD Space: 10 GB or more.

Since the system uses client-server architecture, various networking hardware

requirement arises here, some of those hardware includes:

1] Switches:

8/16 Port Switches Depending on requirement(Recommended Device: Cisco Small Business SD216 10/100 MBps Switch)

2] Router(Recommended Device:Dlink DAP 1350 Wireless N Pocket Router)

C] Software Requirement Specification:

Softwares required for development purpose:

o Microsoft windows XP/2000/7 Operating Systems.

o VS.NET Platform:

(An IDE supporting all .NET Languages)

o Microsoft.NET SDK (Included in VS.NET Platform).

o Microsoft SQL Server 2005.

o IIS (Internet Information Services) Server.

Softwares Required for proper operation at clients site:

o Microsoft Windows NT Server 2003 Operating system.(For server).

o Windows XP, 2000, 7 Operating System (For Clients).

B] Class and Package Diagram:

Since, weve multiple modules for our application, so weve partitioned each and every moduleinto packages, so that our work can be divided between group members efficiently.

IConnection: Its a interface that will provide database connection to every independent

module, this interface also provides other database related services.

Every Module will implement IConnection Interface and will contain certain classes necessary

for implementation of system.
