Introduction to DBMS

A database management system (DBMS) is an important type of programming system, used today on the biggest and the smallest computers As for other major forms of system software, such as compilers and operating systems, a well-understood set of principles for database management systems has developed over the years, and these concepts are useful both for understanding how to use these systems effectively and for designing and implementing DBMS is a collection of programs that enables you to store, modify, and extract information from a database.. There are different types of DBMS, ranging from small systems that run on personal computers to huge systems that run on mainframes. The following are the location of database between application programs and end-users.
There are two qualities that distinguish database management systems form other sores of programming systems.

數(shù)據(jù)庫(kù)管理系統(tǒng)是編程系統(tǒng)中的重要的一種，現(xiàn)今可以用在最大以及最小的電腦上。其他重要
形式的系統(tǒng)軟件，比如匯編以及操作系統(tǒng)，近些年來(lái)開(kāi)發(fā)出一系列容易理解的數(shù)據(jù)庫(kù)管理系統(tǒng)原則
，并且這些概念既有助于理解如何有效利用系統(tǒng)，以可以幫助設(shè)計(jì)和執(zhí)行DBMS系統(tǒng)。DBMS是一
