simple workflow engine

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 c

Chapter One background and objectives I have studied the work flow engine technology for many years, as the research result Superflow, already has many mature applications. I am willing to put these bits of accumulated dedication out, and everyone to share the fun and bitterness of learning. Some people say that 35-year-old programmer in the twilight years, I am 36 this year, just learned the true meaning of the program life. §1-1 Development Backg

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

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

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. Cu
