Why did SAP choose CDS for S/4HANA Analytics?

SAP chose Core Data Services (CDS) for S/4HANA Analytics primarily because it integrates more effectively with application layers. CDS views enable the definition of semantic data models that can be used across different applications and user interfaces, providing a unified approach to data access and manipulation. This integration allows for better performance when accessing data, as it simplifies the process by which applications consume data models.

By leveraging CDS, developers can create a clear separation between data definitions and the application logic, which promotes reusability and consistency across various applications. Additionally, CDS views support advanced functionalities such as annotations that enhance the user interface experience and provide improved metadata, which is essential for analytics.

The other options do not capture the primary reasons behind SAP's choice. For example, while debugging may be simpler with certain tools, the focal point for choosing CDS is its integration capabilities. Similarly, calculation views are still available and can be used in conjunction with CDS where suitable; they do not restrict the use of CDS. Lastly, while visualizations are an important aspect of analytics, CDS's primary strength lies in its ability to integrate and enhance data handling rather than just focusing on visualization.
