What does Database mean?

A Database is a structured and organized collection of data that is stored electronically and can be efficiently retrieved, managed, and manipulated. Databases are essential in various applications, from business operations and e-commerce to web development and scientific research.

Databases consist of tables that store data in rows and columns, and they use database management systems (DBMS) to handle data storage and retrieval operations. Popular types of databases include relational databases (e.g., MySQL, PostgreSQL), NoSQL databases (e.g., MongoDB, Cassandra), and in-memory databases.

Databases are used to store information, support data-driven decision-making, facilitate data analysis, and enable data sharing and integration across applications and systems.
