Semantic Integrity Constraint Types

Business rules are expressed in relational databases by means of various types of integrity constraints. Four types of integrity constraint are supported:

  • Domain
  • Column
  • Table
  • Database
  • These four types of constraints are implemented in distinct ways in Teradata database, though the differences between column and table constraints are subtle.
