How are tables related in a relational database?

Tables in a relational database are related through common fields or keys. These keys establish relationships between different tables, allowing for data to be linked and accessed across multiple tables. Through the use of primary keys, unique identifiers within a table, and foreign keys, which reference the primary keys in other tables, data can be structured and organized in a way that enables efficient retrieval and manipulation of information. This relational structure is essential for maintaining data integrity and ensuring consistency in a database system.
