Chapter 8 Using Business Rules in a PDM
Depending on the type of DBMS, the following is generated regarding check constraints:
| Database type | Generation result |
|---|---|
| Database does not support any check constraints | No constraint is generated |
| Database does not support multiple check constraints | Constraint business rules, check parameters, and validation business rules are concatenated into a single constraint expression |
| Database supports multiple check constraints | First, the check parameters and validation business rules are generated into a single constraint, then the constraint business rules are generated into different constraints. Constraints are thus ordered |
