How do you show referential integrity constraints for Employee Employee ID Employee Name Payroll Address Date Employed Skill Years Employed?

Referential integrity constraints ensure that relationships between tables remain consistent. In the context of an Employee table with attributes like Employee ID, Employee Name, Payroll Address, Date Employed, Skill, and Years Employed, you would establish a primary key on the Employee ID to uniquely identify each employee. If the Employee ID serves as a foreign key in another related table (e.g., Payroll or Skill tables), it must correspond to an existing Employee ID in the Employee table, ensuring that no records in the related tables reference a non-existent employee. This can be enforced through database management systems using foreign key constraints.
