What is required to create a relationship between 'EmployeeID' in the 'Professor' table and 'Advisor' in the 'Student' table?

To establish a relationship between 'EmployeeID' in the 'Professor' table and 'Advisor' in the 'Student' table, dragging 'EmployeeID' to 'Advisor' in the Relationships window while enforcing Referential Integrity is essential. This action creates a direct link between the two fields, allowing the database to recognize how the two tables are connected.

Enforcing Referential Integrity is a critical aspect of this process because it ensures that every entry in the 'Advisor' field of the 'Student' table corresponds to a valid entry in the 'EmployeeID' field of the 'Professor' table. This helps maintain data accuracy and consistency, preventing orphan records where a student references a non-existent advisor. By requiring that all values in 'Advisor' match values in 'EmployeeID', this enforcement helps to uphold the integrity of the relationship across the database.

Other approaches do not necessarily accomplish this goal effectively. For example, merely disabling Referential Integrity does not create a proper linkage between the two fields and can lead to data inconsistencies. Similarly, right-clicking and selecting 'Create Relationship' does not inherently enforce Referential Integrity unless specific options are selected during that process. Lastly, choosing 'Append' from the Database Tools does not relate to creating or managing table relationships but refers to
