Relational Database Theory

Relational database theory organizes data into tables, called relations, where each table contains rows (records) and columns (attributes). Each table represents a specific type of data, and relationships between tables are established through shared attributes, like keys. This structure allows for efficient storage, retrieval, and management of complex data, enabling users to query and manipulate information systematically. The theory ensures data consistency, integrity, and flexibility, making relational databases a widely used approach for managing structured data in various applications.
