What a DBMS does
A DBMS typically supports: - Data definition: creating database structures (tables, fields, relationships). - Data manipulation: inserting, updating, deleting, and querying data. - Data integrity: enforcing constraints (e.g., unique values, valid ranges). - Security: controlling access with authentication and permissions. - Concurrency control: handling multiple users or applications at the same time. - Backup and recovery: protecting against data loss and restoring after failures. Common examples include relational DBMSs (like MySQL, PostgreSQL, and SQL Server) and non-relational DBMSs (like MongoDB), depending on how data is modeled.

Why DBMS matters
DBMSs improve consistency, reduce duplication, and make it easier to maintain large datasets. They also enable powerful querying (often using SQL for relational systems), which helps applications find exactly the data they need efficiently.
