DS STM Models

When implementing model-based refactoring, two key input artifacts form the foundation: the DS (Data Simplifier) and STM (State Machine) files.

DS Model

The DS File represents data structures. including metadata such as structure definitions, system linkage, and headers. Key elements include:

• Groups: Represent hierarchical structures.
• Elementary Items: Represent individual fields.

STM Model

The STM File describes program logic, including methods and state machine definitions. Common elements include:

• Processes: Represent methods or workflows.
• Statements: Cover logic constructs like loops, assignments, and conditionals.
• Expressions: Represent subparts of statements, such as literals or operators.
