Reference Domain

When adding a domain, you can create a subdomain that is lite or standalone. You use the reference domain field to indicate whether the new domain will be lite or standalone.

Oracle Transportation Management provides various domain-specific data such as parameters, business object status codes, notification objects, business number rule definitions, etc. The installation of this data in a domain depends on the type of domain that you create. You can create the following two types of domains:

• Standalone domain: This domain includes all domain-specific data. When you create a new domain in Oracle Transportation Management, a lot of data is copied into that domain that is specific to the new domain; for example, status types and status values.

• Note: If you do not specify a lite domain/reference domain when adding a domain, a standalone domain is created.

• Lite domain: This domain references a standalone domain and the data from the standalone domain is used. A lite domain limits the size of a domain. A lite domain does not have its own complete copy of all the data in several tables, including the following tables:
• • status_type
  • status_value
  • status_functor
  • notify_subject_stylesheets
  • bn_rule
  • domain_setting

Instead, the " Lite" domain will reference the data in its reference domain, which must be an ancestor domain. A lite domain uses a reference domain to supply the data that was not copied to the lite domain when it was created. That is, the data is not copied to the lite domain but resides in the defined reference domain. Using a lite domain saves space in the database by not copying common, shared data. If you do not specify a lite domain then a standalone domain is created. Lite domains may be subdomains.
