Yes, a table can have multiple foreign keys referencing the primary key of another table. Here's a step-by-step explanation:

1. Define the primary key in the first table: This is the unique identifier for each record in the table.

2. Define the foreign keys in the second table: These are fields in the second table that link to the primary key in the first table.

3. Set up the foreign key relationship: This is done using a FOREIGN KEY constraint in SQL. The syntax is: FOREIGN KEY (column1, column2, ... column_n) REFERENCES parent_table (column1, column2, ... column_n)

4. Ensure referential integrity: The database management system checks that all foreign key values point to existing rows in the parent table.

5. Use the foreign keys in your queries: You can now join the two tables on the foreign key relationship, allowing you to retrieve related data from both tables.

Remember, the purpose of having foreign keys is to ensure data integrity and to create relationships between different tables in a relational database.
