Database

A database is an organized collection of data that is stored and accessed electronically. Databases are designed to manage large volumes of information, making it easy to store, retrieve, update, and delete data efficiently. They come in various types, including relational databases like MySQL and PostgreSQL, which use structured query language (SQL) for data management, and NoSQL databases like MongoDB and Cassandra, which handle unstructured data. Databases are integral to modern applications, supporting everything from business operations and customer management to scientific research and social media platforms. They ensure data integrity, security, and accessibility, playing a crucial role in data-driven decision-making and operations.
