E-Vaidya is using client-server system where the user interface of the client is web (browser) and the server is a standalone machine. Most of the request like validation and compression gets completed in client side itself using java-scripts and Ajax but for any request where database access is required the client sends request to server for process. For every process server receives from the client it opens a new database connection, thus for multiple processes it opens multiple connections. The connection gets closed once the process gets completed. E-Vaidya is using EVM (3-tier) architecture, thus all application is between the three layers (a) User Interface, (b) Business/Application Layer/EVM and (c) Database. The diagram below display the EVM architecture.

Business Layer All the applications and logics is written in the business layer. This is basically the server side information. Any user request will be to business layer from user interface layer. Business layer opens connection for the database access.
Database Database contain all the data needed by the application and user interface layer.
