1)Introduction:1.1)Purpose:To deliver next generation police and law enforcement reporting tools,and setting up intelligence platformsthat agencies use to take incoming incident reports,lessen live employee resources and allow these enforcement agencies to reallocate resources to much needed community areas

1.2)Scope:

*Administrator should be able to create/edit a virtual

police station which represents a real police station as a first time setup.

*Appointing of police officers to a particular police station which is present in a specific zone or to a specific district as a first time setup,he should be transferable at later time.

*Police station should have areas of control which can be

modified at later times.

*Police station has several departments like Law and

Order,Women Protection,Cyber crime,Traffic and control,CBI,etc.

*When a complaint is made it undergoes various processes like FIR,Charge Sheet,Property Seizure,court disposal etc all these activities are performed by a Police station.

*Traffic and Control has important part where the Traffic

inspector would be filing a charge sheet from a mobile or PDA.

*Maintaining the criminal information state wise/area

wise/age wise is mandatory. 1

*Sharing of case details with Police station in other states

is needed.

*Communication between officers is mandatory through forum,chat,polls.

*The magistrate should be able to apply for various

licenses like Arms,loud speaker,Hotel/Lodge,browsing center, mass meeting etc, and the officer should be able to approve/reject which will be notified to the applicant via SMS and Mail.

*Secured registration of citizens is needed where they

need to provide proof of citizenship,which will be cross checked by the police officer of that area.

1.3)Abbreviations:*HTML: Hypertext Markup Language is a markup language used

to design static web pages.

*EJB: Enterprise Java Beans.

*J2EE: Java 2 Enterprise Edition is a programming platform— part of the Java Platform-for developing and running distributed multitier architecture Java applications,based largely on modular software components running on an application server.

*DB2: DB2 Database is the database management system that delivers a flexible and cost effective database platform to build robust on demand business applications.

*WAS: Web sphere application server is an application server that runs business applications and supports the J2EE and web services standards.

2

*WSAD: Web sphere studio application developer is a toolkit which is designed for the creation of more complex projects, providing fully dynamic web application utilizing EJB’s . This consist of EJB tools,CMP ,data mapping tools & a universal test client that is designed to aid testing of EJB’s.

*HTTP: Hypertext Transfer Protocol is a transaction oriented client/server protocol between web browser & a Web Server.

*HTTPS: Secure Hypertext Transfer Protocol is a HTTP over SSL (secure socket layer).

*TCP/IP: Transmission Control Protocol/Internet Protocol, the suite of communication protocols used to connect hosts on the Internet. TCP/IP uses several protocols, the two main ones being TCP and IP.

1.4) References:* IEEE SRS Format

* Problem Definition (Provided by IBM)

* CT Arrington. Enterprise Java with UML. OMG Press.

1.5) Technologies:* J2EE: Application Architecture

* DB2: Database

* WSAD: Development Tool

* WAS: Web Server

* Rational: Design Tool

* IBM Lotus Symphony

1.6) Overview: SRS will include two sections:

* Overall Description will describe major components of the system 2 interconnection and external interfaces.

*Specific Requirements will describe the functions of actors, their role in the system an constraints.

2) Overall Description:Describe the general factors that affect the product and itsrequirements.2.1)Product Perspective:

First Tier:Web Clients

Third Tier(DBMS):Database Cluster(s)

Client Browsers

SQL Server

DB2 Database

Internet

Database Cluster

Second Tier: Server Side Web Applications

Other Database

Database Connectivity

Application ServerWeb Server

* The web pages (XHTML/JSP) are present to provide the userinterface on client side. Communication between client and server isprovided through HTTP/HTTPS protocols.

* The Client Software is to provide the user interface on system userclient side and for this TCP/IP protocols are used.

* On the server side web server is for EJB and database server is forstoring the information.

2.2) Software Interface:Client on Internet: Web Browser, Operating System (any)Client on Intranet: Client Software, Web Browser, Operating System

(any)Web Server: WAS, Operating System (any)Data Base Server: DB2, Operating System (any)Development End: WSAD (J2EE, Java, Java Bean, Servlets, XML),

DB2, OS (Windows), Web Server.Software Requirement Specification:IBM Lotus Symphony

2.4) Communication Interface:* Client on Internet will be using HTTP/HTTPS protocol.

* Client on Intranet will be using TCP/IP protocol.

2.5)User Characteristics:Every user should be comfortable of working with computer and net browsing. He must have basic knowledge of English too.

2.6) Constraints:* GUI is only in English.

* Login and password is used for identification of citizen and there isno facility for non-members.

* This system is working for single server.

* There is no maintainability of back up so availability will get effected.

* Limited to HTTP/HTTPS.

9)Conclusion: This Project can be improved later. There somescopes for improvement. Such as:

*Integration of E-cops with Prison Management and Court is an immediate requirement.

*Chat using XMPP provides added feature.

*Biometric Authentication(Face detection or Fingerprint).

*Administrator should have a java client end rather than web end.

*Use of JMS for communication between other state database.

*Predicting criminal faces in various conditions using digital image processing via face points would be additional features.
