Abstract: An intermediary computing device, and related methods, that enhance data analytics operations are provided. An analytics platform appliance associated with the intermediary computing device can obtain and parse a flow text file data structure to identify a transactional source system. A data extraction mechanism can obtain, from the transactional source system and based on information in the flow text file data structure, a source data structure. A data transform mechanism can generate, based on information in the flow text file data structure, a data model structure from the source data structure. The analytics platform appliance can identifies, from the flow text file data structure, presentation data instructions. A data load mechanism can access the data model structure create a display data structure based on the presentation data instructions. The intermediary computing device can provides the display data structure to the end user computing device.
