A Database Management System (DBMS) is software designed to facilitate the creation, management and retrieval of databases. It acts as an interface between users and the actual database by managing the organization, storage and manipulation of data.
The main tasks of a DBMS are
Data organization: structuring data into tables, relations or other formats in order to store and retrieve it efficiently.
Data integrity: Ensuring the accuracy and consistency of data by implementing integrity rules and constraints.
Data access and management: Providing mechanisms for inserting, updating, deleting and querying data.
Security: Implementing access controls and security mechanisms to prevent unauthorized access to data.
Data backup and recovery: Backup of data and recovery in the event of errors or failures.
A DBMS allows users to access and manage data in a structured and organized way, regardless of its complexity or size. It is an indispensable tool in today's data processing and is used in various applications and industries, including finance, healthcare, retail, education and more.
