What is Data Base?


What is Data Base?

An ordered data collection is used to facilitate access and management of a database.
To help you identify important information, organise data into tables, rows, columns and index it.
Database managers design a database to enable access to all users using only one set of software programmes.

An ordered data collection is used to facilitate access and management of a database. To help you identify important information, organise data into tables, rows, columns and index it. Database managers design a database to enable access to all users using only one set of software programmes.

There are numerous available databases such as MySQL, Sybase, Oracle, MongoDB, Informix, PostgreSQL, SQL Server, etc.

The database management system manages modern databases (DBMS).

For operation on the data saved in a database, SQL or Structured Query language is utilised. SQL depends on relation algebra and the calculus of tuples relationships.

Advantage of DBMS-

Controls redundancy:

All data is stored in one database file to control data redundancy.

Data sharing

An authorised user can share the info with several users.

Backup

The Backup and Recovery subsystem is provided. It automatically generates system failure data and, if necessary, recovers data.

Multiple user interfaces

It supports various user interfaces such as GUIs and application interfaces.

Disadvantage of DBMS-

Size

It takes enormous disc space to run efficiently and with vast memory.

Cost

DBMS demands a high-speed data processor with more extensive storage for running DBMS software, which is expensive.

Complexity

DBMS Complexity adds further complexity and demands.
