What defines how you can access data, such as that of a Business Partner or an Asset, from the database in Avaloq Script?

The Data Dictionary is the correct choice because it serves as a centralized repository defining the structure, types, and relationships of data within the Avaloq system. It specifies how data entities, such as Business Partners or Assets, are defined and accessed in the database. The Data Dictionary outlines the available fields, their data types, and any constraints or relationships that must be adhered to when retrieving or manipulating data. This allows developers and users to efficiently interact with the data through Avaloq Script.

Other layers, such as the Service Layer, facilitate communication between the front-end and back-end processes but do not define data access mechanisms. The Business Logic Layer focuses on implementing business rules and processes but is not responsible for defining data access structure. The Kernel Layer primarily manages core functionalities of the Avaloq platform, including application execution environment but does not encompass the specifics of data structure and access. Thus, the Data Dictionary is the key component that enables and structures the way users can retrieve and manipulate data within the Avaloq environment.
