Roles of a database server in web based environments

In today's system environments where information is remotely exchanged over various networks, it is essential to manage data from a secured database server. In fact, in the process of any software product development with a database, client applications (programs which use the data) interact with the database server that stores the data.

A modern database server can efficiently perform multitasking and serve different applications making it ideal for online software development where a huge number of web pages are dynamically generated using the information from the database. Moreover, the added security and data-encryption provided by these database servers give the added advantage for secured online transactions.

The database server mainly performs the following tasks:

• Store the database in a dedicated or distributed system
  
• Maintain data integrity and security
  
• Manage database transaction and authorization

While the front-end application runs on the users' system, the back-end executes operations like data storage and analysis.

The implementation process of a database server involves the following:

• Setting up the necessary hardware and software.
  
• Installation of the database server and the client applications
  
• Data migration from any earlier version (if required)
  
• Configuration settings of the database server
  
  
  • Setting environment variables
    
  • Setting connectivity and configuration files
    
  • Disk allocation and initialization
  
  
• Set the database application and create the database architecture

In general, any offshore software development company prefers to implement the database server as a separate node for managing the database management software. The node provides an interface designed using front-end development tools or web pages for client nodes where users are allowed to post requests for data retrieval. These requests are served through statements written in database query languages which interact with the database. The efficiency of the whole process depends on how the database server is managed and different configuration settings are done by the administrator.
