A relational database stores data in tables that consist of rows and columns. Each table represents a specific entity, with rows corresponding to individual records and columns corresponding to attributes of those records. This structure allows for efficient organization, retrieval, and manipulation of data using structured query language (SQL). Examples of relational databases include MySQL, PostgreSQL, and Oracle Database.
