Abstract

A select query or a data referencing a calculation scenario is received by a database server from a remote application server. The specified calculation scenario is one of a plurality of calculation scenarios and it defines a data flow model that includes one or more calculation nodes. Each calculation node defines one or more operations to execute on the database server. Thereafter, the database server instantiates the specified calculation scenario and executes the operations defined by the calculation nodes of the instantiated calculation scenario to result in a responsive data set. This data set is then provided by the database server to the application server. Related apparatus, systems, techniques and articles are also described.
