First, prefaceIn the previous article I gave you a description of my workflow model and basic design, this article I would like to explain in detail the function of my workflow and use examples. This workflow is mainly designed for developers, in order to let everyone have a global understanding, the design of the local function is not elaborate, the follow-up ti
Below will be the current mainstream of the three workflow to introduce and compare, and then through the three process engine design a more typical process to show you the three process of creating the process. These three workflow engines are Windows Workflow foundation,netbpm, respectively, Ccflow.NETBPM and Ccflow
After reading this article, you must have used the workflow engine as an example of a pure process, and have the foundation of Java, JSP, and HTML. You also know how to read the related javadoc/CHM to view the APIS required for programming.
We use a simple leave process to introduce how to implement a workflow project:
The process is very simple. The programme
Who is responsible for defining and developing workflow applications? There are generally three points of view, that is, our positioning of the workflow engine:
1) The actual technical personnel are responsible for defining and developing workflow applications.
In my opinion, this idea is equivalent to a
I learned and accumulated a lot of workflow knowledge at work, and wrote some personal feelings on the Internet. I think this field can be further explored.
So I am going to start a workflow engine Project Based on. NET.
Because I am familiar with Java open source workflows, my basic idea is to integrate the advantages of these projects into a. Net version.

I have previously raised questions about dual-engine or multi-engine. Many friends ask what the purpose of the multi-engine is. Here, I will give a few simple examples.
The following example is just a reference. Do not lock your mind with the following examples.
1. Use multiple engines for business expansion flexibility

Workflows are used in many business systems, such as office software and review software. Recently, the company needs to develop a workflow engine, which relies on databases. By now, it has basically been completed. Well, I don't like text either. Next I will briefly introduce the basic things. First, the system architecture is as follows:
A workflow (
The workflow reference model determines the basic architecture of the workflow management system. This architecture is a system model that should be adopted when developing workflow software. Of course, a workflow management system may not follow this model standard or only implement part of this model. However, it tur
After learning, using, and developing the workflow engine for so long, agileflow has also been developed to version 0.8, but during this period
I have not found an engine that makes me feel excited. How can I reasonably locate the boundaries of the workflow engine and design
WebService way, so that the service of engine can cross system structure, organize boundary to drive business process flow, This distributed mode greatly plays the function of engine middleware.

Recently, we have been thinking about the following problem: if we want a workflow engine to properly handle any complicated (simple) flow chart designed by users through the process designer, so for this jobThe Structure Design of the stream engine must be flexible, because if we only rely on a limited collection of classes and methods, it is not easy for us to
