Database Management Systems


A database management system, or simply DBMS, is an important programming tool that consists of a set of programs that define, manage and process databases and all applications associated to them. Through this, you are able to build a structure and operate on the valuable data that the database holds in a very efficient way. There are two main types of users that work on DBMS – the conventional user who retrieves or modifies data and the administrator who is responsible for maintaining the structure of the database.

The following are the key features of a DBMS:

• Allows the creation of new databases and their data structures
• Allows data query and modification using an appropriate programming language
• Allows the storage of vast amounts of data over a long period of time
• Enables database recovery in times of failure, error or intentional misuse
• Controls data access from many users at once

It was during the late 1960s when the first commercial DBMS appeared. It evolved from file systems that basically provided data storage for over a certain period of time. Though such systems were capable of storing tremendous amount of data, computer professionals still have to face problems of data loss and an inefficient information retrieval system. There were also issues on control access where errors occur when two users modify the same file at the same time. Some examples of these applications are airline reservation systems, banking systems and corporate record keeping systems, among others.

With the advancement of technology in the market today, you can find numerous programs that will be suitable for your DBMS requirements. There are applications that run on a small scale level like your personal computer or tablet. Some are built to run on a large and powerful equipment, like those being used by multinational companies. Nevertheless, the on-going trend is for DBMS to be executed on multiple platforms or machines (whether large or small) that are interconnected to one another, forming an immense scalable network. IT experts have also found ways on how store data using Internet technology in powerful data centers or more popularly known as clouds. This cloud can be public entity (managed by a large company like Microsoft or Google) or a private one (maintained and stored via the intranet within an organization).
