12.3.12 AttributeAssignment Abstract

   This object provides a mapping between a mining attribute (logical data) and a set of attributes in the input data (physical data). LogicalAttribute is the mining attribute being mapped by this object. OrderIdAttribute is used when ordering of attributes is required. In some cases, ordering of attributes is important (as in sequence analysis). In other cases, a sequence of an attribute is favored over having a set-valued attribute.

   AttributeAssignment can be reused among several tasks, but a MiningAttribute can be referred to by an AttributeAssignment within a task.
