Introduce the following aspects:
Start point model, activation model, operating model, process combination nested model, process integration model, etc. Among them, the operational model of the third section is, and it is a serious medium in this article, and it is more detailed. See the directory structure below.

First, the starting point model of the process
Single Start Node
1.2 starting points
Multiple solutions
Multi-start
Multiple ways three
Second, the activation model of the process
2.1 Artificial activation
2.2 Timing or limited time activation
2.3 External Message Activation
Third, the operation model of the process
3.1 Basic operation model
Serial (SEQUENCE)
Cycle
3.2 Dissive Working Model
Parallel
Exclusive Choice
Diaminator Choice
Cc model
Divergence model
3.3 aggregation operation model
Synchronization polymerization (Synchronize Merge)
Simple merge

DISCRIMINATOR MERGE
Fourth, process combination nested model
4.1 Inclusive
Main process waiting method
Main proximity is also running
4.2 Embedded model
V. Process integration model

The concept of "what is workflow" and workflow is not introduced here. Everyone is interested in watching the WFMC. Here first to talk about personal opinions: a workflow includes a set of tasks (Task) and their mutual sequential relationships, as well as startup and termination conditions for process and tasks, and descriptions for each task. In fact, this is taken from http://www.simflow.neet/workflow/workflow.htm on a description of workflow. It's just the original text called "activity", I changed to the task (task), which may be better understood. In fact, the circle of single workflow has now been jumped, increasingly increasing the nesting or integration between multi-workflow, summary in paragraph 4, 5 later in this article.
In addition to each model, some graphical meanings that appear in this article are required. Save only graphical representations, use icons to replace some process nodes. As shown below:
The meaning of each icon is subsequently explained later.
