A database is an organized collection of structured information or data, typically stored electronically in a computer system. It allows for efficient data retrieval, storage, and manipulation.

SQL (Structured Query Language) is a standard programming language used for managing relational databases. It enables users to perform tasks such as querying data, updating records, and defining database schemas.

SQL is crucial for interacting with databases efficiently. It allows users to retrieve specific information from large datasets, perform complex analyses, and manage database structures effectively.

A typical database system comprises three main components: the data itself (stored in tables), the database management system (DBMS) responsible for managing and accessing the data, and the application programs that interact with the database.

SQL databases, also known as relational databases, organize data into tables with rows and columns and use SQL for querying and manipulation. NoSQL databases, on the other hand, store data in various formats like key-value pairs or JSON documents and are often used for handling large volumes of unstructured data.
