Element Type Definition
| Element Type Name | DOMAIN_CONSTRAINT |
| Short Name | DCO |
| View Name | CI_DOMAIN_CONSTRAINTS |
| Description | A data constraint that will not exist as a database constraint, only |
| as a database trigger. It identifies the use of a domain that has | |
| not been modelled using the DOMAIN element type. The set of valid | |
| values exist in a table that has been modelled and which may be of a | |
| generic nature, containing the valid values for several such domains. | |
| For example: | |
| A table may exist called APP_REF_CODES, which contains the allowed | |
| values for several logical domains, including the domain of valid | |
| job titles. In order for the JOB column in the EMP table to use this | |
| domain, a domain constraint would be created on JOB for APP_REF_CODES. | |
| The definition of the domain constraint includes the specification | |
| of the restriction to apply to the domain table. such as: | |
| APP_REF_CODES.DOMAIN_NAME = 'JOBS' | |
| There would be one KEY_COMPONENT that mapped EMP.JOB to | |
| APP_REF_CODES.DOMAIN_VALUE | |
