What is a relational database?

A relational database is a type of database that organizes and stores data into tables with predefined relationships between them. It consists of one or more tables, where each table is made up of rows (records) and columns (attributes). The tables are related to each other through primary and foreign keys, which establish connections between the data. This relationship enables efficient data storage, retrieval, and manipulation. A relational database allows users to define complex queries and retrieve data based on various criteria, ensuring data integrity and consistency through well-defined relationships. It is widely used for managing structured data in various domains, such as business, finance, and e-commerce.
