Which data modeling technique is NOT used in SAP HANA?

In SAP HANA, hierarchical views are not a recognized data modeling technique. The HANA data modeling framework primarily includes calculation views, analytical views, and attribute views.

Calculation views are flexible and capable of combining data from various sources; they can include both graphical and SQL-based content. Analytical views are specifically designed for multidimensional analytics and support complex aggregations, making them ideal for reporting and analysis. Attribute views serve to model master data and provide reusable dimensions for other views in the system.

Hierarchical views, on the other hand, do not exist in the SAP HANA data modeling environment. While hierarchical data can be represented within other view types, there is no dedicated view specifically for hierarchical structures in HANA's modeling tools. Therefore, identifying hierarchical views as not being part of SAP HANA's data modeling techniques highlights the unique aspects and structure of HANA's approach to data management and analysis.
