What is a key benefit of using CDS views over traditional database views?

The selection of enhanced performance and analytics capabilities associated with CDS (Core Data Services) views highlights a significant improvement over traditional database views. CDS views are designed to utilize the full power of the underlying database, enabling SQL-like expressions, various analytical functions, and logical aggregations that can enhance data processing performance.

Additionally, CDS views allow for annotations that provide not only metadata but also optimization hints, which can significantly improve the execution speed of queries running against them. These views are integrated into the ABAP development environment, allowing for seamless performance tuning and extended analytics, such as support for advanced functions and the ability to implement calculation views, which are beneficial for analytical applications.

In contrast, the other choices do not capture the full breadth of benefits inherent to CDS views. The claim that CDS views support complex joins automatically does not fully encapsulate their capabilities, as traditional views can also handle joins, though perhaps not as flexibly. The assertion that they do not require a database table is misleading; CDS views still depend on the data model and underlying database tables. Lastly, while it's true that CDS views enhance the development process by minimizing the need for some ABAP layers, they do not eliminate the ABAP layer entirely, as ABAP logic is still often necessary for complete
