Which of the following are characteristics of Core Data Services (CDS) views? Note: There are 2 correct answers to this question.

Question

Options

• ACDS views are developed, maintained and extended in the HANA database layer of
• BUse of CDS views supports hybrid transactional and analytical applications, such as SAP Smart
• CThe content of CDS views represents a virtual data model based on the data tables of
• DCDS views speed up reporting by providing a dedicated persistency layer.

• A
  78% (31)
• B
  8% (3)
• C
  15% (6)

Explanation

Note: The stated correct answers (A and D) appear to conflict with standard SAP documentation. Based on well-established CDS characteristics, B and C are the correct answers. Here's why:

Why B and C are correct:

• B is correct because CDS views are a foundational enabler of SAP's HTAP (Hybrid Transactional/Analytical Processing) strategy - the same dataset can serve both operational transactions and analytical reporting without data replication.
• C is correct because CDS views define the Virtual Data Model (VDM) in S/4HANA - they are semantic, reusable abstractions layered on top of physical database tables, with no data stored in the view itself.

Why A and D are incorrect:

• A is wrong because ABAP CDS views are defined and maintained at the ABAP application server layer, not the HANA database layer. HANA-native CDS is a separate concept.
• D is the opposite of reality - CDS views are virtual by design and provide no persistency layer. Reporting performance comes from HANA's in-memory column store, not from CDS storing data separately.

Memory tip: Think "CDS = Virtual + Versatile." Virtual means no storage of its own (kills D), and Versatile means it serves both transactions and analytics (supports B). The VDM sits above the tables (supports C), not inside HANA itself (kills A).

You may want to verify this against your course material, as the answer key you have (A and D) does not align with standard SAP S/4HANA documentation.
