The schema's top-level object is a 'DataObjectMappingList'. It is an array of individual source-to-target mappings called 'DataObjectMappings', commonly referred to as 'mappings'.
In code, this means a DataObjectMappingList is defined as a List of
A DataObjectMapping is a unique ETL mapping / transformation that moves, or interprets, data from a given source to a given destination. The decision to start the format with an array / list that contains potentially multiple DataObjectMappings relates to the Data Warehouse virtualization use-case. In these implementations, multiple individual mappings together create a single view object. As an example, consider the loading of a Core Business Concept / Hub type entity from various different sources. If you would use these different mappings to generate ETL processes you would create one physical ETL object for each mapping. However, if you are seeking to generate a view that represents the target table the result you would use the collection (list) of mappings to generate separate statements that are unioned in the single view object.
