Database Management Systems

A database management system (DBMS) is software that stores and organizes data in a systematic way for efficient access and retrieval. It manages databases by providing facilities for creating, modifying, and querying databases. DBMS provides facilities to define, manipulate, and manage databases, including the ability to create tables, indexes, views, and relationships between them. A DBMS acts as an intermediary between the user and the database, allowing users to interact with the data without having to know the intricacies of the underlying storage technology. DBMS supports various operations such as CRUD (Create, Read, Update, Delete) for managing data in the database, along with querying capabilities like SQL queries. Some popular DBMS include relational databases like MySQL and PostgreSQL, document-oriented databases like MongoDB, and key-value stores like Redis.
