Guide to Database Management Systems (DBMS)

A database management system (SGBD), sometimes simply called a database manager is a program to create one or more computer users and access data in a database allows. The DBMS manages user requests (and requests from other programs), allowing users to freely and other programs have to understand where data is physically located on a storage medium and in a multi-user, access may be on different dates. During the processing of user requests, the DBMS ensures the integrity of the data (that is, he must continue to be accessible and is consistently organized as intended) and safety (ensuring that those with access rights can access the data). The most typical DBMS is a management system, relational database (RDBMS). A standard user and programming interface is the Structured Query Language (SQL). A new kind of DBMS is the system of object-oriented database management (SGBDO).

In terms of operating data, information, conduct its business, the DBMS must be able to solve various kinds

of applications. Typically, the need is to find out your customer base, the most valuable customers or clients that are currently being created only to the costs for you. What is the current situation, which was two years ago? How is it developed? Or is it? Without specially designed DBMS, which contains historical data, there is absolutely no way to grow your business based on facts and are only good guesses. Historical data is combined with easy to use productivity tools for the end user can help you, and that is why Sybase IQ is the DBMS of your data warehouse or data mart applications. Specially designed for the analysis of questions that you do not even know, but Sybase IQ is lightning fast, easy to say that the same DBMS stores all your historical data in less space than your DBMS operations. Innovative design and patented indexing structures shorten the reaction time from days to minutes and hours to seconds - no matter what your current IT infrastructure.

A DBMS can be used as file manager, which manages data will be considered in databases instead of files in file systems. Operating systems in the IBM mainframe, were the non-relational data manager (and, as these still existing application systems are used), known as access methods. A DBMS is usually an integral part of a product database. On PCs, Microsoft Access is a popular example of an individual or small groups of DBMS user. Microsoft SQL Server is an example of a DBMS, the database serves several requirements (client) users. Other popular DBMS (RDBMS are they all, by the way), IBM DB2, Oracle Product Line Management Database, and Sybase products.

IBM Information Management System (IMS) has been one of the first DBMS. A DBMS can be caused by or in conjunction with transaction managers, such as IBM Customer Information Control System used system (CICS).
