Database Management System
A Database Management System (DBMS) is software that enables users to define, create, maintain, and control access to databases. It provides an interface for performing operations like data insertion, querying, updating, and administration, ensuring data integrity, security, and efficient storage. DBMSs abstract the physical storage details, allowing applications to interact with data through structured query languages or APIs.
Developers should learn DBMSs when building applications that require persistent, structured data storage, such as web apps, enterprise systems, or data analytics platforms. They are essential for ensuring data consistency, supporting concurrent access, and implementing business logic through transactions and constraints. Knowledge of DBMSs is crucial for backend development, data engineering, and system design roles.
