Which objects are created when a Data Definition is activated?

When a Data Definition is activated in the context of SAP's Core Data Services (CDS), a CDS View is created as part of the process. Activating a Data Definition essentially involves defining a structured data model that can be accessed by various applications within the SAP ecosystem. This model becomes a reusable component, which is represented as a CDS View once it has been activated.

The concept of a CDS View is central to the SAP HANA environment, where it serves as a semantic layer over the database, allowing developers to create complex data queries with simplified syntax. This activation process allows the CDS View to be recognized within the system and provides the necessary metadata for other applications to utilize the defined data model efficiently.

In contrast, while other options pertain to data handling in SAP, they do not specifically refer to the direct output of activating a Data Definition. For instance, an Activation View is not a standalone object that directly results from the activation process, and a Data Definition View is a conceptual label rather than a recognized physical object in the system. SQL Views can also be related but may not necessarily form part of the direct outcome of activating a Data Definition. The primary creation resulting from the activation is indeed the CDS View, making it the correct choice.
