A Database Management System (DBMS) is a set of programs that controls the creation and use of databases for an organization. A DBMS represents complex relationships between data, controls data redundancy, and ensures data sharing and security through user-defined rules. It provides benefits like flexibility, fast response to queries, lower training costs, and reduced storage needs. However, implementing a DBMS also involves costs like hardware, software, training, and potential database damage. Common DBMS models include hierarchical and relational models.

2.  A Database Management System (DBMS) is a set of
computer programs that controls the creation,
maintenance , and the use of the database of an

 For examples- the list of names and address may consist of
only a few hundred records, each with a simple structure.

4. • Represents complex relationship between data
• Controls data redundancy
• Ensures data sharing
• Enforces user defined rules
• It has central dictionary to store information

5. • Flexibility

• Less storage

6. • Cost of hardware & software
• Cost of data conversion
• Cost of staff training
• Appointing technical staff
• Database damage

7. • Data Definition Language (DDL)
• Data Manipulation Language (DML)
• Data Control Language (DCL)

8.  HIERARCHICAL MODEL

12.  This information clearly throws light on various
functions of DBMS which it can perform in day to day
life of a person. DBMS models broadens its activities
depending on the purpose of activity. Its increasing
demand and application of it in the business gives a
clear picture of its scope and importance of it in the
business world as well. It gives a bird eye view of a very
complex data and also helps in easy finding of the
relations between different components of the data.
