1. A computer-implemented method comprising: receiving a request for an input schema to feed to a data specification language (DaSL) and a metadata outline of typed objects exposed by a database view identified in the request, the database view associated with the database selected using a graphical user interface; requesting extraction of the input schema and metadata outline from the database; creating an instance of a DaSL compiler based upon the input schema; generating, by a computer, a DaSL query corresponding to objects selected from the metadata outline, the DaSL query including low-level primitive queries compiled into a computing language construct supported by the database, mapped to a specific DaSL operator, dynamically compiled at query runtime, and executed to retrieve data from the database conforming to the request; requesting compilation of the DaSL query; receiving a calculation plan and topology cursors responsive to the compilation of the DaSL query; and initiating visualization of a dataset responsive to the execution of the calculation plan using the topology cursors.

The method of claim 1 , further comprising compiling the DaSL query into the calculation plan and topology cursors used to visualize data.
