4.2.1 ARCHITECTURE

To develop the System for online billing three tiers architecture is maintained and the model will work both with standalone application as well as client server model. The database and application resides on the same machine. Client working on the application perform different operations on the database and database manipulate the request and generate the result.

Typical role of client side:-

• The client should gather all needed information before making a request to the server.
• The client is responsible for all display of data to the client.
• The client should handle all data manipulation operations.
• The client provides all formatting of data and presentation of information in reports.

Typical role of server side:-

On server side the operations are broken into logical components. The server should create the result set that the client side application require.

Client-Server approach introduced a database server to replace the file server. Using RDBMS user queries could be answered directly. The client/server architecture reduced network traffic by providing a query response rather than total file transfer. It improves a multi-user updating through a GUI front end to a shared database. In client-server architecture, Remote Procedure Calls (RPC s) or Structured Query Language are typically used.


Advantages of client / server:-

The client/server architecture reduced network traffic by providing a query response rather than total file transfer. It improves a multi-user updating through a GUI front end to a shared database. It also increases performance of our application. With SQL Server, we can implement true client/server system.

DATA MODEL

As per requirement the information that is to be stored in database is:-

1. Information about User’s Bill (like name, address, phone etc.)

2 Login details (like user name, password etc.)
