1. Introduction

1.1. Purpose:

Virtual Medical Home steps in where doctors and medical facilities are just a dream. It helps connect rural areas, eliminate barriers and provide them medical assistance which is the fundamental right of every human being. It provides live online consultations, medicine prescriptions, 24x7 medical assistance and regular health alerts. It also maintains records of a registered patient’s health history and medical reports.

1.2. Scope:

• Allows various system users to register.• Provides essential medical services online to everyone. It hardly matters

weather the user lives in city or a remotely located village.• Allows user to make online appointments with a doctor, the system

provides first aid tips and information in case of accidents or common diseases.

• The software also advices doctors on medical and treatment options and alternatives.

• Doctors can access the lab reports and medical history of patients (users).• Web conferencing and instant messaging between user and doctor is

possible

1.3. Acronyms:

• 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.

1.5. Document Overview:

The remainder of this document is two sections, the first providing a full description of the project.

• Overall Description will describe major components of the system, interconnection and external interfaces. It lists all the functions performed by the system.

• Specific Requirements will describe the functions of actors, their role in the system and constraints. This section concerns details of each of the system functions and actions in full for the software developer’s assistance.

These two sections are cross-referenced by topic; to increase understanding by both groups involved.

2. Overall Description:

The Virtual Medical Home encompasses numerous files and information from the Database, as well as files on the server system. This system will be completely web-based, linking to the remote web server from a standard web browser. An Internet connection is necessary to access the system.

2.1. Product Perspective:

This part of the SRS puts the product into perspective with other related products. A block diagram showing the major components of the Virtual Medical Home system, interconnections, and external interfaces is given below:

• The web pages are present to provide the user interface on customer clientside. Communication between customer and server is provided through HTTP/HTTPSprotocols.

• The Client Software is to provide the user interface on system user client side and for thisTCP/IP protocols are used.

• On the server side web server is for EJB and database server is for storing the information.

• Registration section• Verification section• Log-In section• Profile updates section• Communication section• Admin section

6

• Medical Suggestions Section• Help section

Registration section:

In this section the user will make the registration by providing his/her details like name, gender, address, mail-id etc. Under this section we are having two parts: one for the common man and the other for the doctors.

Note: Doctors have to attach their scan copy of their degree, license documents and along with a recent photograph.

Verification section:

Under verification section the software will verified the user. For all the users their details are checked by the authority and then a verification mail containing the user name and a password will be send to the user’s email-id.

Log-In section:

An authentication process is there during the log in request made by the users.

3.2. Supplementary Requirements:

Have hours of operation that are 24 x 7 - Because system can be an automated process, so it can stay open for 24 hours a day. If the base is now the entire world, staying open 24 hours a day becomes critical. System is required to be available 24X7 so UPS support must be on server site for at least 8 hours in case of power failure. System will remain inaccessible to users at 2:00 to 4:00 am for backup and maintenance purpose.

Make the existing Web site more dynamic in nature - Many early Webimplementations consisted of static HTML pages. This becomes very difficult to manage if the number of pages gets too large. An effective system should be largely dynamic taking advantage of technology that automates this process rather than relying on manual processes. Application should serve dynamic user based customized web pages to its clients from server.

Tie the existing Web site into existing enterprise systems – Any existing Web site that relies on the manual duplication of data from another system is one that can be improved. Most of the business data in the world today exists in enterprise servers that can be connected to the Web servers to make this process far more effective.

Provide good performance and the ability to scale the server – The WebApplication Server should provide good performance and the ability to manageperformance with techniques, such as support for caching, clustering, and loadbalancing.
