Teradata Retrieval Architecture

The key steps involved in Teradata Retrieval Architecture are:

1. The Parsing Engine sends a request to retrieve one or more rows.
2. BYNET activates the relevant AMP or AMPs for processing.
3. The AMP or AMPs locate and retrieve the requested rows through parallel access.
4. BYNET returns the retrieved rows to the Parsing Engine.
5. The Parsing Engine delivers the rows back to the requesting client application.
