  Key Concepts: 
  CDS (Core Data Services) is a data definition language used to define and consume semantically rich data models in SAP HANA. It is part of the ABAP programming model and provides an abstract behavior definition for the RESTful ABAP Programming Model. This allows developers to define data models that can be used in both ABAP and HANA applications. 
  
  How to use it: 
  The CDS abstract behavior definition is used to define the behavior of a data model. This includes defining the structure of the data, the relationships between different elements, and any additional logic that needs to be applied. The CDS abstract behavior definition can then be used to generate a RESTful API that can be used to access the data model from an external application. 
  
  Tips & Tricks: 
  When defining a CDS abstract behavior definition, it is important to consider how the data will be used in both ABAP and HANA applications. This will help ensure that the data model is optimized for both environments. Additionally, it is important to consider how the data will be accessed from an external application when designing the RESTful API.
