The most effective approach to establish foreign keys for three adjacent tables is to use a chain of Foreign Key constraints.
For example, if Table A has a primary key that is referenced by Table B, and Table B has a primary key that is referenced by Table C, then you can set up foreign key constraints to enforce referential integrity between the tables as follows:
This approach ensures that the values in the foreign key columns of Table B and Table C actually exist in the corresponding primary key columns of Table A and Table B, respectively. This helps to maintain data integrity and consistency across the three tables.
