Abstract

A database server receives a multi-part query from a remote application server. The multi-part query specifies a calculation scenario defining a data flow model that includes a plurality of calculation nodes that include a main section of nodes and two or more branches of 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 additionally executes the operations defined by the calculation nodes of the main section of the instantiated calculation scenario a single time and executes the operations defined by the calculation nodes of the branches to result in respective responsive data sets corresponding to each branch. The responsive data sets are then provided by the database server to the application server. Related apparatus, systems, techniques and articles are also described.
