Which of the following entities is NOT a type found in data vaults?

• A. Hubs
• B. Links
• C. Satellites
• D. Tables

Answer: (D)

In the context of data vault modeling, the correct answer focuses on the foundational constructs used to represent and manage data effectively within a data vault architecture. Hubs, links, and satellites are the three core components of this methodology. Hubs represent the unique business keys and are designed to capture the major entities in a business environment. They provide a central point for tracking the core data. Links, on the other hand, serve as the connective tissue between hubs. They establish relationships between different business keys, allowing for the modeling of associative data without creating dependencies between entities. Satellites are used to store the descriptive attributes related to the hubs and links. They provide the historical context and additional information that may change over time, thereby supporting the tracking of changes in business processes. Tables, while a common term in database terminology, do not refer to a specific entity type within the data vault methodology. Instead, tables can represent a variety of structures in a database context, but they are not categorized as a core component of data vault architecture. This distinction makes tables the option that does not align with the specific entities defined in the data vault framework.
