        In the 1960s, the use of main frame ready reckoners became widespread in many companies.

check to Martine, in 1981, a database is a share collection of co-ordinated data designed to meet the postulate of threefold types of dying users. The data is stored in one localisatio n principle so that they are independent of ! the programs that use them, keeping in thought data integrity with respect to the approaches to adding new data, modifying data, and retrieving alert data. A database is shared and perceived differently by multiple users. This leads to the reach of Database Management Systems.         These systems first appeared around the 1970=s as solutions to problems associated with mainframe computer computers. Originally, pre-database programs accessed... If you want to get a full essay, revision it on our website: OrderEssay.net
