A Database Management System (DBMS) is software used to store and manage data. A DBMS stores data in databases and uses data models to show the various ways of managing data.
A database is a collection of logically related data. Data means known facts, which are meaningful and canbe recorded. For example, names, telephone numbers, and addresses. You can record this data in an indexedaddress book or on a hard disk, by using software such as Microsoft Access or Microsoft Excel. Using adatabase for storing and accessing data provides lots of benefits over the traditional approach of storing datain the flat text files.
Database Management is the task of maintaining databases so that the information is easily available. The software required to perform the task of database management is called a DBMS. DBMSs are designed to maintain large volumes of data.
Management of data involves:
- Defining structures for data storage.
- Providing methods for data manipulation, such as adding, editing, and deleting data.
- Providing data security against unauthorized access.
DBMSs are now available on a wide range of computers, from desktops to mainframes. The size and powerof a computer determine the system facilities, such as security and storage. DBMS also allows the abstractionof data at different levels.
The main advantages of using DBMS are:
- It provides an efficient and easy way to store, update, and retrieve data from a database.
- It manages information about the users who interact with DBMS and the tasks that these users canperform on the data.
A Relational Database Management System (RDBMS) is an advanced version of a DBMS that also defines the relationship between the various data values. This feature helps in managing and using data more efficiently than DBMS.
It is a collection of programs and capabilities that enable IT teams and others to create, update, administer and otherwise interact with a relational database. RDBMSes store data in the form of tables, with most commercial relational database management systems using Structured Query Language (SQL) to access the database.
