Parent and child tables in relational databases
Parent and child tables in relational databases are fundamental concepts that define the relationships between different tables. In this structure, a parent table contains the primary key, while the child table holds a foreign key that references the parent table’s primary key. This relationship helps maintain data integrity and establishes connections between related data across multiple tables. Understanding parent-child relationships is essential for designing efficient and normalized databases, enabling users to perform operations such as joining tables, ensuring consistency, and enhancing query performance.
