1. Which type of declarative processing provides the ability to proactively obtain data needed for processing by resolving a series of triggered dependent property values changes?

Forward chaining is a declarative processing method that starts with known facts and derives new facts by applying rules. When property values change, forward chaining proactively triggers dependent property changes in a cascade, working forward from the initial change to resolve all affected properties. This differs from backward chaining, which works backward from a goal to determine what facts are needed.
