What role do symbolic names play in the source Message Structure?

Symbolic names in the source Message Structure play a crucial role as they directly become the field names in resulting Data Dictionary Definitions (DDICs). This means that when messages are constructed and defined within the system, the symbolic names act as placeholders that represent the actual data fields. These names provide a meaningful way to reference the data, allowing for easier understanding and manipulation of the data structures involved. By establishing clear, descriptive field names, developers and users can more readily interpret the data and utilize it effectively within the Avaloq Message Interface framework.

The other options, while they may pertain to various aspects of message processing, do not accurately describe the primary function of symbolic names in the message structure. For instance, symbolic names are not related to data encryption, message categorization, or priority levels; instead, their primary function revolves around establishing clear and direct links to the fields represented in the database schema.
