The so-called workflow engine refers to the workflow as a part of the application system, and provides core solutions such as information transmission routing and content level that have a decisive role in each application system according to different roles, division of labor and conditions. The workflow engine includes important functions such as process node management, flow direction management, and process sample management.
What is a Workflow Engine (Workflow Engine)
For example, the most critical part of developing a system is not the interface of the system, nor the exchange of information with the database, but how to develop program logic that meets actual needs according to business logic and ensure its stability and ease of maintenance (modularity and ease of maintenance). Structure) and flexibility (easy to make procedural changes according to changes in actual business logic, such as changes in decision-making rights, changes in organizational structure,
and
new business logic due to changes in business direction, etc.). The Workflow engine solves this problem: if an application lacks a strong logic layer, it is bound to become error-prone (misrouting information, infinite loops, etc.).
Just like a car, no matter how beautiful the exterior is, if there is a problem with the engine, it is just a decoration. The flexibility of the application system is like the performance of the engine speed. It takes 1 hour to accelerate to 100 kilometers (the changes in the business process require half a year of program modification). Is it still a good car? Do you dare to drive a car whose engine stops at every turn (the program falls into an infinite loop due to logic problems)?
