Abstract: 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.

Abstract: Systems and method for using flash variables as import parameters for a dashboard in a portal environment are presented. One or more values that define a portal environment that displays a graphical dashboard are determined. The dashboard is adapted to display in the portal environment graphical representations of data from a data source connected with a backend system. A flash object is generated for retrieving selected data from the data source connected with the backend system based on a request for the data from the dashboard, and for generating the graphical representations for the dashboard. One or more flash variables corresponding to the one or more values are generated, the one or more flash variables defining the selected data of the data source to be retrieved based on the one or more values. The one or more flash variables are inserted into the flash object for retrieving the selected data from the data source.
