What Is Dbms?

The definition I'm most familiar with is as an abbreviation for 'DataBase Management System' which is a description of the way data is stored, accessed and manipulated on a particular computer system.

Until about 30 odd years ago, (when of course computers wrre generally much larger and less sophisticated than today), data was stored in a kind of hierarchy, with major records having subordinate records stored alongside them. Logical you'd think but in fact not very efficient when it came to speed of processing. Things improved with the advent of the network (or codasyl database which used algorithms for organising data location within the secondary memory (disk based filestore).

When spreadsheet software arrived, the way they organised data, directly paved the way to the RDBMS (Relational DBMS) which is in use today (Microsoft Access within MS-Office is an example) and these are truly dynamic.

            A database management system(DBMS) is a software system that integrates data in storage and provides easy access to them. The data themselves are placed on disk in a database, which can be thought of as an integrated collection of related files. Although not all databases are organized identically, many of them are composed of files, records and fields. For instance, the Product file contains five records one each for skis, boots, poles, bindings, and wax. Finally each record consists of distinct types of data called fields. The product file stores four fields for each record product name, product number, supplier, and price.

            Database management software enables queries and reports to be prepared by extracting information from one file at a time, and, as we will shortly see, from several interrelated files concurrently. Database management system (DBMS) A software product designed to integrate data and provide easy access to them. Database is a integrated collection of related data files and Relational database management system is a computer program for database management that links data in related files through common fields. Database management system stores data in relevant form and give easy access to them. The data placed on disk themselves.

DBMS is the short form of Database Management System.It  is a system which manages coherent data  and represent a relationship between them.It also makes sure that this data can be shared across different application and enforce data access  authorization.It also possess automatic backup  and recovery procedures which can be accessed whenever needed.The DBMS has different interfaces through which users can manipulate data.

DBMS is a Database Management System as software program to be manage a database,which program enable users to access modify database.
