Staging Schemas

1. Definition of Staging Schemas:
• A staging schema is an optional area where you can temporarily store data during the execution of a mapping.
• It is used for intermediate data storage, which can help with transformations or data processing.
2. Specifying a Staging Area:
• You can specify a staging area for a mapping or for a specific physical mapping design within a mapping.
• The staging area allows you to handle data before moving it to its final target.
3. When to Define a Staging Area:
• If you want to define a different staging area than the source or target datastores, you must explicitly define the correct physical and logical schemas.
4. Defining Logical and Physical Schemas:
• Before creating a mapping, make sure to define the correct physical and logical schemas in the execution context of the mapping.
• This ensures that the staging schema is set up properly and is distinct from the source and target datastores.
5. Mapping Execution Context:
• The execution context is where you define the schemas that will be used during the execution of the mapping.
• It ensures that the right staging, source, and target schemas are applied during the mapping process.
