A method and system for externalizing conditional logic for an integrated programming architecture provides a static tree structure traversed by a dynamic object collector. The tree structure includes a plurality of conditional nodes and a plurality of branches for testing at least one conditional statement. Each conditional node associates with one conditional object for testing conditional statements and one or more aspect objects. The plurality of branches establishes sequential links between a first conditional node and later conditional nodes. Evaluation instructions evaluate conditional statements relative to the conditional object. An object collector is instantiated for a particular set of data, such as a business event. Upon instantiation, the object collector cache and collected objects set is empty. Object collector traverses tree structure according to the evaluation result of the condition objects of the encountered condition nodes. Object collector evaluates this condition.
