Integrity Constraints for SAS Tables

SCL provides a set of functions that enable you to work with integrity constraints (IC). Integrity constraints are a Version 7 feature of SAS software for preserving the consistency and correctness of data that is stored in SAS tables. When integrity constraints are assigned to a table, they are automatically enforced for each addition, update, and deletion action on that table.

The new IC functions are ICCREATE, ICDELETE, ICTYPE, ICVALUE.
