In SAP S/4HANA,Core Data Services (CDS)provide a universal language to define and consume data models across different applications. CDS enables the creation of semantically rich data models that can be consistently used in various scenarios, ensuring uniform data processing and retrieval.
Option A: SAP HANA
This option is incorrect. SAP HANA is the underlying in-memory database platform that stores and processes data but does not provide the universal modeling language.
Option B: SAP Business Suite
This option is incorrect. SAP Business Suite is a set of integrated business applications but does not offer a universal language for data modeling.
Option C: Core Data Services
This option is correct. CDS defines data models that can be used across various applications, providing a consistent and unified approach to data handling.
Option D: SAP Fiori
This option is incorrect. SAP Fiori is a user experience design
SAP S/4HANA’s architecture includes layers that enable data processing and application functionality. The question asks for the layer providing a universal language to read and process data across applications. Let’s analyze the options:
A. SAP HANA: This is the in-memory database layer powering SAP S/4HANA. While it provides the technical foundation for high-speed data processing, it does not offer a universal language for applications—it’s a platform, not a data abstraction layer.
B. SAP Business Suite: This refers to the legacy ERP suite (e.g., ECC), not a layer of SAP S/4HANA. It is a collection of applications, not a data processing language or layer, making it incorrect.
C. Core Data Services (CDS): This is the correct answer. CDS is a semantic layer in SAP S/4HANA that provides a universal language to define, read, and process data across different applications. Built on the SAP HANA database, CDS uses a SQL-based syntax to create reusable data models (views) that simplify access to data for applications like SAP Fiori, analytics, and extensions. It ensures consistency and efficiency, a key feature of S/4HANA’s architecture, including the Private Edition.
D. SAP Fiori: This is the user interface layer of SAP S/4HANA, providing a modern UX via apps. It consumes data but does not define or process it universally across applications, making it incorrect.
In conclusion, Core Data Services (CDS) is the layer in SAP S/4HANA that provides a universal language for data processing.
