DBMS NOTES ALL BASIC

 Database: A database is a collection of related data which represents some aspect of the real world. A database system is designed to be built and populated with data for a certain task.


Database Management System (DBMS) is a software for storing and retrieving users' data while considering appropriate security measures. It consists of a group of programs which manipulate the database. The DBMS accepts the request for data from an application and instructs the operating system to provide the specific data. In large systems, a DBMS helps users and other third-party software to store and retrieve data.


Database management systems were developed to handle the following difficulties of typical File-processing systems supported by conventional operating systems.


1. Data redundancy and inconsistency


2. Difficulty in accessing data


3. Data isolation – multiple files and formats


4. Integrity problem


5. Atomicity of updates
