Forward Chaining: It
provides the automatic calculations of the property value by executing the
declarative rule, when any one of the input property value is changed.
EX: If the Area property depends on
the Length and Width property, then forward chaining causes the Area property
recomputed each time either
Length/Width value changes.
Length/Width value changes.
·
Backward Chaining: It
provides the automatic calculations of a property value by executing the
declarative rule, when a value is needed for property rather than whenever
inputs change.
EX: If the Area property depends on the Length and Width property, then backward chaining causes the Area property recomputed each time the Area property is required.
