A Database Management System (DBMS) is software that allows users to store, retrieve, manage, and manipulate data efficiently. It provides a structured way to organize and handle large amounts of data while ensuring data integrity, security, and consistency.
Some popular DBMS software includes MySQL, PostgreSQL, Oracle DB, Microsoft SQL Server, and MongoDB.
