FOREIGN KEY Meaning and Definition

1. A foreign key is a term commonly used in the field of relational databases to define the relationship between two tables. It is a column or a set of columns in one table that refers to the primary key of another table, establishing a link or connection between them. The purpose of a foreign key is to enforce data integrity and maintain the relationship between the tables.

   In simpler terms, a foreign key enables the identification and linkage of related information across different tables in a database. It ensures that there is consistency and accuracy in the data by implementing referential integrity. It creates a connection between tables and allows data to be shared and referenced between them, resulting in more efficient and organized data management.

   When a foreign key is implemented, it restricts the values that can be inserted into the column, ensuring that only values from the referenced table's primary key are allowed. This constraint guarantees that data in the related tables remains synchronized and eliminates the possibility of orphaned or invalid records. Additionally, foreign keys enable various operations such as joins, cascading updates or deletions, and can play a significant role in data retrieval and manipulation during database queries.

   Overall, foreign keys are crucial components in relational databases that establish relationships between tables, promote data integrity, and enhance the overall efficiency and reliability of a database system.
