Let's take a look at what is a workflow?
The so-called workflow engine means the workflow as part of the application system, and provide decisive effect on each application system delivery core routing, content ratings, and other information solutions based on different decision roles, division of labor and conditions. The workflow engine includes a node management process, the flow of important functions of management, process management, and other samples.
Like a car, then it does look beautiful, if there is an engine problem just a decoration. Like elastic application system performance aspects of engine speed, accelerating to 100 km requires one hour (business process procedures need to be changed six months of modification) also applauded car? Engine stalling at every turn (because of procedural problems of logic into an infinite loop) car dare to open it?
XJR workflow development platform is the integration activity workflow engine graphical process designer, through a visual configuration interface. Based B / S structure, pure browser application, need only drag and drop components, splicing process, the layers can be achieved approval. Both for data integration between internal workflow OA office systems, such as loan and reimbursement, budget and final accounts and so on, but also to achieve data integration between OA Office Workflow with other business systems, such as HR, ERP, CRM, etc. .
In OA office system, everyone will leave with the process, we leave the application process to take an example, take a look at how to use XJR rapid development platform to visualize the design process? Before creating a work flow we need to pass XJR rapid development platform visual form designer to design a leave of absence form design. There is an article in detail introduced earlier, and here is not explained in detail. Demo: https://www.xjrsoft.com/
First, click on the background workflow process design → 
Second, leave the process designer to draw a flow chart, XJR rapid development platform is designed to integrate activtity process development, using visual editing workflow engine, auxiliary professional R & D design process functions, I like this only office software people can easily get started, learn to save costs and improve efficiency.
Leave Process: Applicants submit leave forms, first in charge, and then by the personnel manager for approval, vice president for approval. Supervisor, manager for approval if the leave days than or equal to greater than three days after the approval of the deputy chief of personnel required for final approval, leave days less than three days, the final approval of personnel. The process ends.
Third, process design permission settings.
Fourth, the approver to add settings
Fifth, we will form the established leave hanging in the process. 
Six, leave flowchart - flow condition setting. Here to please patients, for example, transfer conditions are leave days.
Seven, to see the completed process. Test process tasks.
XJR rapid development platform complete with engine model, through its process engine, do not need to understand technology, do not need to write code, combined with a set form of visualization can quickly create ERP, OA, CRM, HRM, EAM, BI, PMS and other software .
