in enterprises, there are many workflows, leave procedures, and overtime procedures, salary Increase process and so on. In many systems, the workflow design is defined in Program development, but this often cannot meet the changing needs of customers. For example, during design, we define the overtime process, A send a request to the department manager. The manager reviews the request and then gives the answer. This simple process is complete. However, the company suddenly stipulated that all the leave procedures must first go through personnel (for example ). In this way, our original process will not go any further. And so on, making changing workflows more complicated.
The following requirements are of course applicable to workflows:
1.Allows users to customize workflows in any depth
2. tracking process operations at all times. (Because you are concerned about your salary increase request, you are there .)
3. based on requirements, quick Change Process
4. participants can be broadly defined, such as roles, positions, and departments.
With these four requirements, I am a newbie who is deeply troubled. The following are some of my ideas. I hope you can give me some advice.
My thoughts:
1. I first checked, TCP/IP transmission of information packets. The two are similar.
Each node, that is, the participant, can receive, process, and forward messages.
TCP/IPOur process
source request initiation
destination receiver
confirmation number Current Status
data request content
at the same time, we can add the urgency in our messages, must be handled by (like WSDL mustunderstand .
another point here is that the response message of any node is only sent to its direct message source. And TCP/IP the same is true. No relevant materials are found. L
2. flexible processes:
design a syntax parser to parse the process set by the client.
For example: employee A request salary increase:
Suppose our syntax is as follows:
P: Personnel
D: Department
DM: Department manager
HR: Personnel
M: General Manager
This process can be described as follows:
(P) % DM % _ HR _
If, on that day, the requested salary increase must be approved by the General Manager at the end
(P) % DM % _ HR _ % m %
In this way, our parser reads the process description language to extract the specific process.
These are some of the initial ideas, certainly not mature, and even fatal errors. You are welcome to discuss them extensively. Thank you very much!
This grammar is parsed fromInterpreterMode.
