Which of the following features of an XS Advanced application are provided by an HDB module?

The selection of virtual data modeling as a feature provided by an HDB module in an XS Advanced application is accurate because HDB modules are specifically designed to manage native HANA database objects. This includes the capability to create and manage calculation views, which serve as the basis for virtual data models.

HDB modules utilize the in-memory capabilities of SAP HANA to allow for complex data processing and analytic calculations without requiring physical data movement. The ability to create both analytical and transactional models directly aligns with the concept of virtual data modeling, where users can dynamically access and manipulate data without duplicating it.

In contrast, while user interface elements and business logic can be part of XS Advanced applications, they are typically handled by other components such as UI modules or Node.js modules, rather than the HDB module specifically focused on database objects. Similarly, while persistence is related to the handling of data and storage, it encompasses various aspects, including table definitions and data manipulation, that extend beyond the singular definition of virtual data modeling provided by HDB modules.

Understanding the specific role of HDB modules within XS Advanced applications highlights their focus on enabling sophisticated data modeling and complex analytic capabilities directly within the SAP HANA environment.
