Process Variables

Process variables are key-value pairs that store data within a process instance. They can be accessed and modified by tasks during process execution.

Variable Types

Pythmata supports the following variable types:

• String
• Number (Integer/Float)
• Boolean
• JSON/Dictionary
• List/Array
• Date/Time
• Binary Data

Defining Variables

Variables can be defined in several ways:

1. Process Definition
2. Process Instance Creation
3. Task Execution

Variable Scope

Variables have different scopes:

• Process Level
• Sub-process Level
• Multi-instance Level

Best Practices

1. Use meaningful variable names
2. Document variable purposes
3. Consider variable lifecycle
4. Handle variable persistence
5. Implement proper error handling
