Provides a project-level global variables creation and management feature, allowing users to pre-create global variables for subsequent use in script and workflow development. Note that variable naming conflicts and unintended modifications should be avoided to prevent adverse effects on the data processing.
The main purposes of variable settings are as follows:
Data Transfer: Facilitate data sharing between different nodes in the data processing task flow, making workflow node actions more flexible and enabling more complex operations.
Improve Readability: Defining commonly used variables as global variables can make the code more readable and allow the use of these variables across multiple development nodes. This also makes the code more concise, maintainable, and easier to debug.
Reduce Code Complexity: In some cases, several related variables with certain logical relationships are needed. Defining these variables as global variables can reduce code complexity and simplify the program's logical structure.
