2.  IS A COLLECTION OF PROGRAMS THAT MANAGES THE DATABASES STRUCTURE AND CONTROL ACCESS TO THE DATA STORED IN THE DATABASE.

3.  DBMS performs several important functions that guarantee the integrity and consistency of the data in the database.

4.  Dbms stores definitions of the data elements and their relationships in a data dictionary.  All programs that access the data in the database work through the dbms.

5. Dbms creates and manage the complex structures required for data storage, thus relieving you from the difficult task o defif defining and programming the physical data characteristics. Modern DBMS systems provides storage not only for the data but also for related data entry forms or screen

6.  DBMS transforms entered data to conform to required data structures. For ex. Imagine an enterprise database used by

7.  DBMS creates a security systems that enforces user security and data privacy.  Security rules determine which users can access the database, which data items each user can access, and which data operations the user can perform.  Data administration- examines data security and privacy issues in greater detail.

8.  To provide data integrity and data consistency, the dbms uses sophisticated algorithms to ensure that multiple users can access the database concurrently without compromising the integrity of the database.

9.  Dbms provide backup and data recovery to ensure data safety and integriy.

10.  DBMS promotes and enforce integrity rules, thus minimizing data redundancy and maximizing data consistency.

11.  DBMS provides data access through a query language.  Query language- is a nonprocedural language—one that lets the user specify what must be done without having to specify how it is to be done.

12.  Also provide data access to programmers via procedural (3gl) languages such as cobol, C, PASCAL, visual basic and C++  Also provides administrative utilities used by the DBA and the database designer to create, implement, monitor, and maintain the database.  Structured query langua ge-is the de facto query language and data access standard supported by the majority of DBMS vendors.

13.  DBMS accept end-user requests via multiple, different network environments.  For ex. The dbms might provide access to the database via the internet through the use of web browsers such as mozilla firefox or Microsoft internet explorer.

14.  End users can generate answer to queries by filling in screen forms through their their preferred web browser.  The dbms can automatically publish predefined reports on a web site.  DBMS can connect to third party systems to distribute information via e-mail or other productivity applications.
