• property factName
as %DeepSee.Datatype.string(MAXLEN=255,XMLPROJECTION="attribute");
Optional. If defined, this specifies the name of the column in the Fact table that
corresponds to this element.
If not provided a fact name will be synthesized from the source property and expression
values.
This property should be used cautiously; giving multiple members the same fact name
can lead to logical flaws in the resulting cube definition. If in doubt, do not
use this property.
• property factSelectivity
as %DeepSee.Datatype.string(MAXLEN=255,XMLPROJECTION="attribute");
Optional. If defined, this specifies the SELECTIVITY value for the fact property
corresponding to this element.
This value is not used by DeepSee.
This provides the ability to override the default selectivity for cases when SQL
is used directly against the generated fact table.
• property linkClass
as %DeepSee.Datatype.className(XMLPROJECTION="attribute");
Optional. Class name referred to by linkProperty.
Refer to linkProperty for details.
• property linkProperty
as %DeepSee.Datatype.propertyName(XMLPROJECTION="attribute");
Optional. If defined, then this is the name of a property within the class specified by
linkClass that supplies the value for this element.
The value provided by sourceProperty (or sourceExpression)
is used as the ID of an instance of class linkClass.
If linkProperty is defined, then linkClass
must also be defined.
• property sourceExpression
as %ZEN.Datatype.expression(LANGUAGE="OBJECTSCRIPT",XMLPROJECTION="attribute");
Optional expression used to get the value of this member.
This can refer to properties of the source table using the
syntax: "%source.Property".
An expression can also contain a reference to a class method
of the cube definition class using the syntax: "%cube.Method()".
If sourceExpression is defined, then sourceProperty
is ignored.
• property sourceProperty
as %DeepSee.Datatype.string(XMLPROJECTION="attribute");
Name of the property in the source data that provides the
value for this element.
Using dot syntax, it is possible to refer to a property within
a related class, for example "City.Name" or "City.State.Name".
