Classification Constraints

• Basic constraints

  • Establish minimum levels for attributes
  • e.g., ?(Name) ? U; ?(Salary) ? C

• Inference and association constraints

  • Protect against information leakage
  • e.g., lub(?(Name), ?(Salary)) ? S

• Classification integrity constraints

  • Include primary key, referential integrity
  • e.g., ?(A) ? ?(B)
