Which of the following is NOT a component of the Integration Data Tiers?

The Integration Data Tiers in Teradata involve several components that work together to integrate data from various sources for analysis and reporting. Common Keys, Derived Values, and Summarization are all integral parts of this process.

Common Keys are essential as they allow for the identification and merging of related data from different sources, ensuring that the data can be accurately integrated. Derived Values refer to the new data points created based on existing data, providing additional insights. Summarization involves aggregating data to present higher-level insights, which is critical for analytical purposes.

Access, however, does not refer to a specific component of the Integration Data Tiers. While access to data is necessary for any data processing or analysis, it is not categorized as part of the Integration Data Tiers themselves. Instead, access generally pertains to how data is retrieved or interacted with in the Teradata environment but does not fit within the structured components of integration. This distinction clarifies why access stands apart from the other choices in this context.
