Abstract: A system includes reception, from a client device, a database query over a first data source and a second data source, the first data source comprising a first linking entity and the second data source comprising a second linking entity, the first linking entity identified by two or more columns of the first data source defining a first hierarchy, linking of the first data source and the second data source on the first linking entity and the second linking entity, execution of a blended query on the linked data sources based on the database query to generate a result set, and transmission of the result set to the client device.

Abstract: A system includes reception of a user selection of at least two dimensions of a data source, acquisition of data of the data source, the data associating each of a plurality of dimension values of a first dimension of the selected dimensions with one or more of dimension values of a second dimension of the selected dimensions, determination, based on the acquired data, of graph nodes representing dimension values of the first dimension and graph edges connecting the graph nodes and representing dimension values of the second dimension, generation of a graph image comprising the graph nodes and graph edges, and transmission of the graph image to the user.

Abstract: A method for selectively enabling requests includes There is a first list of in-development backend capabilities and a second list of ready-for-release backend capabilities. There is a third list of in-development middleware capabilities and a fourth list of ready-for-release middleware capabilities. There is a fifth list including backend capabilities which are exposed to a user interface by middleware capabilities, the fifth list being an intersection of the second list and the fourth list. There is a sixth list of development capabilities by taking an intersection of the first list and the third list combined with an intersection of the second list and the third list. Input is accepted from the user interface moving selected development capabilities from the sixth list to the fifth list. Requests from the user interface directed to the backend are selectively enabled to allow only requests directed to backend capabilities of the fifth list of capabilities.
