Detailed Description

FdoUniqueConstraint can be used to specify that a property or list of properties taken together have unique values for all objects of that class in a datastore. A unique constraint that is based on a list of two or more properties is called a composite unique constraint. This constraint type applies to all data property types except for Boolean, BLOB, and CLOB. A Boolean property can be included if it is part of a composite unique constraint.
