A dependency is a many-to-one data relationship where one or more attributes determine the value of another attribute within a single entity. You can add a Dependencies process to a Quality workflow to create permanent dependencies from attributes in the input entity or the output of the Load process.
After you run the process, drill down to see the permanent dependencies created.
Guidelines
Note the following:
- You add a Dependencies process to a real entity only; you cannot create or discover dependencies for dynamic entities.
- You can add an Analysis process or another Load process off of a Dependencies process.
- Permanent dependencies that you create are different from dependencies that are automatically discovered when you first create an entity or run the Load process; discovered dependencies are potential dependencies you must verify before they become permanent. For more information about profiling data with dependencies, see About Dependency Analysis.
- The Dependencies process creates dependencies using the attributes that you specify. If you want to discover potential dependencies on a sample of data instead, use the Load process.
- Before you can add a Dependencies process to a Load process, you must first run the Load process.
