Database Server

Database Server

A database server is a computer system or program that provides database services to other computers or computer programs. Typically, client applications access database servers over a network.

Database servers are gaining importance because of the increasing popularity of the client/server architecture model in computing. Data stored on a Database Server is setup on a dedicated computer system/server which is accessed concurrently. Database servers maintain data integrity,handles transaction support and also user authorization.

As per requirements of the client server model, an application is divided into front end and back end by the Database Server.The front end runs on the user’s computer and displays requested data. The back end runs on the server and handles tasks such as data analysis and storage.

Implementation of a Database Server

A database server can be implemented in a straightforward manner as separate node (on a network) dedicated to running database-management software. This node provides an interface to client nodes such that the same data is accessible to all nodes. The interface allows users to submit requests to the database server and retrieve information. These requests are typically made using a high-level query language such as SQL (standard query language).

Database Server perform all intensive works such as data manipulation, compilation, and optimization, and sends only the final results back to the client. Database servers are typically made to run on a UNIX operating system.

Benefits of using a Database Server

*  A database server allows users to store data in one central location.

* It performs complex functions such as searching, sorting, and indexing on the server itself. This reduces network  traffic because fewer items need to be transferred between the client and the server.

* Because data is stored centrally, there is enhanced security.

* A database server uses its own processing power to find requested data, rather than sending the complete data to the  client so that the client searches for the data, as is done in a file server.

* A database server allows concurrent access to data.

MySQL Database Server

MySQL is a multi-threaded, multi-user database management system which is available for both, Linux and Windows.It’s a is a free, open source product commonly used by thousands of websites with various web applications using it as their default database.

MySQL is famous or rather more loved amongst the professional folks because of it’s multiple choice in custom storage engines. You can have custom storage engines developed in MySQL based on your requirements or choose amongst the inbuilt ones.

MS SQL Server

SQL Server is a server based database & is a more robust database management system. It was designed to have many hundreds, or even thousands of users accessing it at any point in time. Microsoft Access on the other hand, doesn’t handle this type of load very well. This makes SQL Server perfectly suited for database driven websites

MS SQL Server also contains some advanced database administration tools that enable organizations to schedule tasks, receive alerts, optimize databases, configure security accounts/roles, transfer data between other dissimilar sources, and much more.

Oracle Database Server

Oracle Database or Oracle RDBMS is a relational database management system marketed by Oracle corporation.

Features of earlier versions are still being maintained  even if the new version is implemented along with new features.One important aspect is Oracle databases tend to be backwards compatible. Oracle is user friendly and its features can be esily learned
PostgreSQL Server

PostgreSQL is an object-relational database management system (ORDBMS). It is released under a BSD-style license and is thus free software. As with many other open-source programs, PostgreSQL is not controlled by any single company, but relies on a global community of developers and companies to develop it.
