英语翻译
Databases are usually designed to manage large bodies of information.This involves definition of structures for information storage（data modeling）,provision of mechanisms for the manipulation of information（file and systems structure,query processing）,concurrency control if the system is shared by users,and providing for the safety of information in the database（crash recovery and security）.
The DBMS manages user requests（and requests from other programs）so that users and other programs are free from having to understand where the data is physically located on storage media and,in a multi-user system,who else may also be accessing the data.In handling user requests,the DBMS ensures the integrity of the data（that is,making sure it continues to be accessible and is consistently organized as intended ）and security （making sure only those with access privileges can access the data）.
