Embodiment Construction

[0015] figure 1 is a flowchart of a data flow for executing a Web service according to an embodiment of the present invention. This embodiment provides a method for executing a data flow of a Web service. Wherein, in step S10, an execution tree or directed execution graph of the Web service is created, which includes multiple execution paths, and an execution path includes multiple nodes and connections between nodes. Nodes receive input data, process the data, and output the processed data. The process of execution is the process of executing data flow through the connection between nodes. Nodes in the execution path are generally nodes for obtaining data, computational nodes, or Web service nodes, and so on.

[0016] In step S15, the node for acquiring data may check whether the data source has changed. Here, the HTTP protocol can be used to determine whether the data source of the node has changed, and other protocols can also be used to determine whether the data sourc...

Abstract

The invention provides a method and a system for executing a data stream of a Web service. The method comprises the following steps: creating an execution tree of the Web service; responding to the change of a data source of a node or responding to the change of the data processing logic of a node and determining a changed path so as to determine a path requiring to be renewedly executed; executing the path requiring to be renewedly executed, wherein the execution tree comprises a plurality of execution paths, and each execution path comprises a plurality of nodes and connections among the nodes. Once the execution tree is created, when the data stream requires to be renewedly operated next time, if the execution path of the data stream is not changed, for example the place for receiving data of a node is not changed, only the data source is changed or the data processing logic is changed, the execution tree does not need to be renewedly created according to the method and the system, but the execution paths can be reduced.

Description

technical field [0001] The present invention relates to Web services, and more particularly to methods and systems for executing data flows of Web services. Background technique [0002] Web services are generally based on Web protocols. Web services can be used to create products, business processes, B2B interactions, etc. on the Internet or Intranet. Data flow refers to the movement of data across a system from ingress to destination. [0003] Connections between distributed Web services are usually described using data flows. Wherein, a Web service call is represented as a step, and a data connection between Web services is represented as a connection between steps. A connection can also be used to represent a data connection between a Web service and a data operation, such as filtering and sorting. [0004] In the prior art, to execute a Web service, generally an execution tree or a directed execution graph is created first. An execution tree or directed execution g...
