Dictionary Record -- Domain Section

In data management and database design the term "domain" refers to a list of all the permissible values for a data element. For example, if you have a table that collects information about people you may have a column for gender. The domain for gender would likely be "M", "F". In mdEditor Domain objects are described for a Dictionary in the Domains section of the Dictionary Edit Window and later attached to Attributes while defining or editing Entities.

When no Domains have yet been defined for a Dictionary the Domains section will display a large blue box stating "No Domain Found".
