What is a Database?
A database represents an organized collection of data stored and accessed electronically from a computer system. The power behind these databases is harnessed by specialized software known as a Database Management System (DBMS). This system manages data according to a predefined schema, ensuring efficient retrieval, update, and management of data.
Database Management Systems (DBMS)
There are primarily two types of DBMS:
- Simple DBMS: Similar to a modern digital card index, these systems are straightforward and geared towards less complex database needs.
- Programmable DBMS: Accompanied by a programming language, these systems offer sophisticated tools to analyze and manipulate the stored data extensively.
On larger systems, DBMS often interacts seamlessly with other programs, utilizing the database’s functionalities to enhance data utilization and applicability.

- Data Bank: Often interchangeable with ‘database’, a data bank specifically refers to a collection of multiple databases.
- Data Warehouse: An advanced type of database specifically designed for query and analysis, rather than mere transaction processing.
- Management Information System (MIS): Focuses on managing information systems to meet the decision-making needs of an organization.
