The present disclosure involves systems, software, and computer implemented methods for automatically providing delta query support for backend databases. One example method includes identifying annotations for a data set. The annotations indicate data fields of the data set to be used for a delta calculation. A request for a delta calculation is received for the data set. A set of delta calculation queries are automatically generated based on the annotations and a set of query templates in response to the request for the delta calculation. The set of delta calculation queries are executed to generate a delta calculation result. The automatically generated delta calculation result is provided in response to the request for the delta calculation.
