Database

A database is a structured collection of data organized and stored in a way that allows efficient storage, retrieval, modification, and management of information. Databases are used to store various types of data, ranging from text and numbers to images and multimedia. They are an essential component of virtually every software application, including web applications, mobile apps, desktop software, and more.

Data Organization: Databases provide a structured way to organize and store data, making it easier to manage and query information.

Data Integrity: Databases enforce rules and constraints to maintain data integrity, preventing inconsistencies or errors in the stored data.

Data Manipulation: Databases enable users to add, update, and delete data, ensuring that information remains accurate and up to date.

Relational vs. NoSQL: There are different types of databases, including relational databases (e.g., MySQL, PostgreSQL) that use structured tables and NoSQL databases (e.g., MongoDB, Cassandra) that use flexible, schema-less formats.

Indexes: Databases use indexes to speed up data retrieval by creating optimized pathways to specific data points.
