Embodiment
Below in conjunction with embodiment the present invention is done further explain.
Graphical design of a kind of universal workflow and verification tool, characteristic are architecture two parts that comprise universal workflow architecture, flow scheme design and verification method:
1, universal workflow architecture: the flow scheme design means that the general visual flow scheme design device that graphical design of universal workflow and verification tool provide is provided convenience for the user, i.e. flow operations, nodal operation, connecting line operation, amplification dwindled, the control information operation; The user uses general visual flow scheme design device to carry out the design of universal workflow, then the universal workflow of designing is saved as (XML (EXtensible Markup Language) form) general file of quick-reading flow sheets net pattern storage; And then be flow process adapter of every kind of work flow operation platform development, and the universal workflow of designing is imported the operation of Domino platform by the flow process adapter, obtain the flow process transformation result of Domino platform; The information that last actual work flow operation instance produces all is kept in the work flow operation platform.
2, the architecture of flow scheme design and verification method: the architecture of flow scheme design and verification method is divided into visible process and represents layer, XML (EXtensible Markup Language) layer and database layer: represent layer and use AJAX (Asynchronous JavaScript and XML)+VML (Vector Markup Language) technology; Additions and deletions flow process, additions and deletions node, additions and deletions connecting line be provided in the operation of flow process, node, connecting line, pull node, pull connecting line, the expansion of labyrinth with fold, duplicate and paste, align and amplify reduction capability, and give node control information for the flow nodes of graphic process; XML (EXtensible Markup Language) layer provides the calling interface of flow nodes foundation with combination for representing layer; Be responsible for converting the mapping result of node control information control information into describe half formalization procedural model with the XML file layout to the limit; Then the flow process of combination is carried out the correctness verification, and carry out flow process and preserve; Database layer is responsible for the persistence of design cycle, preserves flow definition through the XMLtoNotes function and in the Lotus database, supplies workflow engine to call, for XML (EXtensible Markup Language) layer provides the persistence service.
When graphical design of the universal workflow of embodiment of the present invention and verification tool, three aspects below the main consideration: universal workflow, flow scheme design function, flow verification function, describe respectively below.
One, universal workflow:
1, the implementation of universal workflow is: with the result of flow that XML (EXtensible Markup Language) data layout design Storage goes out, preserve procedure information with the form of simple Work flow model; And then, realize the bidirectional data interaction of universal workflow and real work stream engine through adapter with the Data Source of XML (EXtensible Markup Language) file as adapter.
2, have versatility in order to make instrument of the present invention design workflow, the result of flow that the present invention goes out with XML (Extensible Markup Language) data layout design Storage, preserve procedure information with the form of simple Work flow model:<workflow>...</Workflow>(flow process);<step>...</step>(node);<mxCell>...</mxCell>(graphically);<edge>...</Edge>(flowing to the limit); And then with the Data Source of XML (Extensible Markup Language) file as adapter; Through corresponding adapter (for example; Change the Notes adapter through XML (Extensible Markup Language)) realize that universal workflow and real work flow the bidirectional data interaction of engine (for example, the workflow engine of Domino).So, workflow engine is no longer bound with specific workflow design instrument, as long as possess the adapter of workflow engine, just can obtain the support of universal workflow instrument.
Two, flow scheme design function: the framework of flow scheme design device adopts MVC (Model-View-Controller) pattern.What the M layer was corresponding is the flow definition model, comprising: Workflow (flow process), Step (node) and Edge objects such as (connecting lines); Representing of the corresponding flow process element of V layer, comprising: objects such as WorkRender, StepRender and EdgeRender, the responsibility of these objects are patterns that the decision flow process represents, and just in process flow diagram, see the pattern of flow process; The C layer is a key-course, comprising: add node, deletion of node, change nodename, mobile, selection operation.The front end of flow scheme design device adopts AJAX (Asyn chronous JavaScript and XML)+VML (Vector Markup Language) exploitation; The Java exploitation is adopted on the backstage; When preserving flow process; Send the HttpService request through AJAX (Asyn chronous JavaScript and XML) to Java; Pass to java applet to flow process with the form that XML (Extensible Markup Language) layout character flows,, preserve flow definition in database by the persistence that Java accomplishes flow process.
Three, flow verification function:
1, the key point of flow verification function is: transfer the node control information in the visible process to the limit control information.For after the single flow nodes of visible process figure gives node control information, the overall correctness of whole workflow then can be combined by each node correctness; Utilize predefined business demand semanteme in the system again, can verify the correctness of flow process automatically by system.
2, flow verification function of the present invention is the basis with the simple process flow net, and core is a flow nodes; And then give node control information for flow nodes, be the mapping ruler that corresponding flow nodes is provided with the control information to the limit of node control information according to business demand; Here; The most important point is exactly to transfer the node control information in the visible process (for example will pass through " leader's audit " node at least behind " dispatch drafting " node in the practical business, could get into " text is affixed one's seal " node) to limit control information (for example not allowing to exist a limit from " dispatch drafting " node to " text is affixed one's seal " node) in the flow verification function.For after the single flow nodes of visible process figure gives node control information, the overall correctness of whole workflow then can be combined by each node correctness; Utilize predefined business demand semanteme in the system again, can verify the correctness of flow process automatically by system.
