Abstract: Techniques and solutions are provided for processing query requests from a software application, such as one having a user interface model, using an analytical data protocol that accesses an analytic query. Often, user interface models access data using transactional data protocols, which can limit analytical actions that can be performed through a user interface, particularly actions altering data presented or a data format as compared with pre-defined analytical objects. A query request associated with a user interface query model is received and converted to be executable using at least one analytical query model object. The request, in an analytical protocol, is submitted to a virtual data model. The query request in the analytical protocol is converted to be used with an analytic query defined in the virtual data model. The converted query request is executed against a data store and query results are returned to a user interface layer.
