DBMS means database management system. DBMS contain information about a particular enterprise.  DBMS is collection of inter-related data which is used to retrieval, creation, insertion and deletion of data from database. DMBS is a software tool is used to perform an operation on data in database. It is used to store the data and retrieve the data in an effective manner. It provides more protection and security to data in database. DBMS allows multiple used to work at same time on it and also maintain consistency.

Database Definition:

Database is a collection of related data and data is a collection of facts and figures that can be used to produce the information.

A DMBS is a software package, designed to perform an operation on data that data can be stored and managed in database. It allows multiple users to work on database. It allows multiple users to work on database at same time and also provides security and protection to database. It managed to maintain the data consistency.

Database management system us a tool for managing information and a course on the principles and practice of database system. It is a integral part of computer science.

Curricula: It is a course that covers the principles of database system and explains how they are used in developing data intensive applications. DBMS is a software that interacts with end user applications.

DBMS also contains ER models and relational models that explain how databases are created and, covers the basics of database design and querying treatment by using SQL. [Structured query Language] queries.

The data design and tuning part contains a discussion for performing the tuning and designing for secure access.

“It is a software package designed to store and manage the database.”

DMBS is a collection of inter-related data and set of programs accessing those data in a efficient, convenient manner. DBMS used to maintain, query large database.

Benefits include recovery from system crashes concurrent access quick application development data integrity and security.

Database system vs File system:

File system Database System
Data redundancy and inconsistency There is no data redundancy and inconsistency
In a file system accessing of data is difficult. There is no difficult in accessing data in database
There is a data isolation in file system. Database system does not contain data isolation
In file system there is a atomicity problem No atomicity problem in database system
There is an integrity problem in file system There is no integrity problem in database system
File system contains security problems. Database system doesn’t contain any security problems
Concurrent access anomalies to multiple users There are no concurrent access anomalies to multiple users
It is a collection of data, any management with the file system users has to write the processor DBMS is a collection of inter-related data and users has not required the processor for managing the database.
The file system gives the details of the data representation and storage of data. DBMS provides and abstraction view of data that hides view of data.
File system doesn’t provide crash recovery mechanism. DBMS has crash recovery mechanism. If anything, happen to the system
Data access takes a lot of time. Data access requires less time.
Transaction concept not use Transaction concept is very important.
