Which factors are no longer necessary due to the optimizations in ABAP on HANA?

With the improvements and optimizations brought by ABAP on HANA, the need for individual coding logic specific to HANA has been significantly reduced. Traditionally, development required specific adaptations and optimizations for different database systems due to their varying architectures and performance characteristics. However, since ABAP is now designed to leverage the in-memory capabilities of HANA inherently, developers can utilize the existing ABAP logic without needing to write special code just for HANA.

This shift allows developers to focus more on business logic and less on database-specific optimizations. It enhances efficiency and ensures that applications can take advantage of HANA's speed and performance without unnecessary complexity in the coding process. Consequently, the utilization of standard ABAP constructs is typically sufficient to perform optimally on the HANA platform.

The other factors mentioned, such as manual database management, extensive data modeling, and complex query definitions, may still have some relevance depending on specific project needs but do not directly relate to the need for individual coding logic for HANA.
