Working with Streaming Decision Table

Overview

After you create a decision table artifact, you can build rules for the artifact.

ModelOps offers the following rule building options:

• Adding action and action columns directly from the UI
• Using the Edit Schema button to manage the artifact’s rules
• Using the Undo and Redo button to undo and reapply most recent changes
