Considering the mixed modeling approach, what can you do an SAP HANA calculation view exclusively?

Question

Options

• ACompress datasets by Aggregation
• BGenerate a Rank column
• CCombine datasets by Union
• DSelect a dataset by Projection

• A
  5% (3)
• B
  9% (5)
• C
  2% (1)
• D
  84% (46)

Explanation

Projection (D) is the operation exclusive to Calculation Views within the mixed modeling approach because a Projection node is the mechanism used to select specific columns and filter rows from a data source - including Analytic Views and Attribute Views consumed as inputs - making it the defining "entry point" operation when mixing view types in a Calculation View.

Why the distractors are wrong:

• A (Aggregation): Aggregation is the primary purpose of Analytic Views in the mixed approach, not something exclusive to Calculation Views.
• B (Rank): While Rank column generation is a Calculation View feature, it is a specialized optional output operation, not the defining characteristic of what a Calculation View does exclusively in the mixed modeling context.
• C (Union): Union combines multiple datasets and is a Calculation View node type, but the question focuses on what is exclusively associated with a Calculation View as opposed to what Analytic and Attribute Views already handle.

Memory tip: Think of it this way - in mixed modeling, each view type has a job: Analytic Views aggregate, Attribute Views provide master data, and Calculation Views project (select) from all of them. The Projection node is the "selector" that pulls the right columns from upstream views into the Calculation View logic.
