Abstract: A computer-readable medium, computer-implemented method, and system are provided. In one embodiment, a business process is created, and a cost of change value for the business process is defined. An executable process that is generated from the business process is executed, and a change request is received. It is determined whether the cost of change value is greater than a threshold value, and, when the cost of change value is not greater than the threshold value, the change request is initiated.

Abstract: A distributed order orchestration system is provided that includes an event manager configured to generate and publish a set of events based on a process state and metadata stored in a database. A set of subscribers can consume the set of events, and each subscriber can execute a task based on the consumed event.

Abstract: A distributed order orchestration system for orchestrating a business process of an order fulfillment system receives from an interface a definition of the business process and generates metadata from the definition. The system then generates an abstract syntax tree from the metadata. The tree includes a plurality of nodes and one or more of the nodes correspond to a predefined template. The system then generates executable orchestration code based on the abstract syntax tree and the predefined template.

Abstract: Techniques for dynamic service invocation and dynamic service adaptation in the context of a service oriented application. In one set of embodiments, a plurality of mediator services are introduced between the application and a plurality of actual services accessed by the application. The plurality of mediator services are configured to expose a common, abstract operation. At application runtime, the application determines, via a rules engine, a selection of a mediator service, and invokes the abstract operation by sending an invocation message to the selected mediator service. The selected mediator service transforms (i.e., adapts) the message into a format appropriate for invoking an actual operation exposed by an actual service associated with the selected mediator service. The selected mediator service then invokes the actual operation by sending the transformed message to the actual service.

Abstract: A computer-readable medium, computer-implemented method, and system are provided. In one embodiment, an original executable process is executed in a regular mode. When a change request is received, the original executable process is stopped, and a new executable process is created. The new executable process is then executed in a change mode.

Abstract: A computer-readable medium, computer-implemented method, and system are provided. In one embodiment, a task layer service pattern is created, and a task layer service is created from the task layer service pattern. The task layer service is assigned to a step of an executable process, and the step of the executable process is executed. The task layer service is executed in order to invoke a fulfillment service.
