Abstract: The present invention teaches in general how to efficiently exploit active database technology and extensible database technology, i.e. triggers and user-defined functions for processing subscriptions. According to a first aspect of the present invention it is proposed to aggregate all subscriptions on a certain table, or more generally of a plurality of tables, into a single trigger on this table or tables, respectively. This will dramatically improve the trigger-based efficiency. According to a second aspect of the present invention it is proposed to deliver the information a subscriber has registered for directly out of the database systems address space via appropriate user defined functions which is another source of efficiency improvement.

Abstract: The present invention provides a computerized method for determining an addressee of a signaling request within a Workflow Management System or a computer system with comparable functionality (WFMS). Upon receiving a signaling request, which is providing a set of signal data elements, the current invention avoids the requirement that the signal data elements comprise any explicit specification of an addressee of said signaling request. To determine whether an event-activity of a process-instance being the instance of a process-model of a business-process is the potential addressee of the signaling request it is suggested to determine, whether the process-model comprises an event-identification-specification. This event-identification-specification according to the current invention is involving a subset of the signal data elements. Evaluating the event-identification-specification allows to indirectly decide if the event-activity is the addressee of the signaling request.

Abstract: A computerized transaction execution with a workflow management systems (WFMS) executes a process model consisting of a network of potentially distributed activities including transactional work items. A computerized methodology defines, controls and processes a collection of a transactional work items ensuring the atomicity of the collection of transactional work items. The collection of transactional work items owns a separate commit scope not influenced by a commit scope potentially implemented within said transactional work items. The WFMS is enabled to infer details of the process model of collections of transactional work items which can be processed in the sense of global transactions with a common commit scope. Transactional work items with a common commit scope are combined into atomic spheres. The collection of transactional work items constitute a common atomic sphere in an alternative embodiment.

Abstract: A method of optimizing a workflow management system (WFMS), the method being executable by the WFMS on at least one computer system. The WFMS accesses a database comprising of at least one process model and instantiations of the process model (process instances). The method contemplates transferring objects of the database to an archive database (archive function). This transfer is preferably carried out in case that a predetermined event occurs or if these objects are not currently used by the WFMS. Preferably the objects to be transferred to the archive database are process instances. These process instances are preferably selected among all instances of a certain process model depending on the value of certain properties of this process model. The objects of the database which are transferred to the archive database can also be process models. Additionally the data that is managed by the applications that implement the various activities of the process model can be transferred too by having user programs moving the data from the regular application store to an application archive store. Furthermore the method contemplates transferring the WFMS objects back to the WFMS database as well as transferring the data in the application archive store back to the application store when the archived WFMS objects are needed again (restore function).

Abstract: A control connector (204) connects to a transitional condition (P) to define possible control flow from source activity (S) to target activity (T). The source activity is transformed into a trigger event that, if performed in runtime, tells the trigger system that a source activity's instance is terminated. The control connector is transformed into a trigger condition (205) to assess a TRUE value for the transitional condition
