Abstract: A workflow application comprises several components each performing a defined function, one or more completion steps, the components and completion steps forming a graph and the components being designated as primary tasks which can be paired with one or more components designated as compensating tasks. The graph is interpreted and executed such that each time a primary task is run the compensating tasks associated with it are not run but are added to a compensation group. A completion step completes a subset of the compensation group, the completion step preferably indicating success or failure for a subset of the compensating group and the compensating tasks being run or not accordingly.

Abstract: A workflow application in a data processing system is represented by a graph comprising a plurality of components, some of which may be processes. At least two of the processes are implemented according to different respective sets of rules. The sets of rules are preferably implemented in either a plurality of navigation engines or in a single navigation engine implementing multiple sets of rules. The invention is preferably implemented in a builder-type development and execution environment for the programming of a business application.
