Abstract
A calculation engine of a database management system is described that determines a multiprovider includes a first data source and a second data source that each require different approaches for operation optimization. The calculation engine can split the multiprovider into a first node corresponding to a first operation compatible with the first data source and a second node corresponding to a second operation compatible with the second data source. The calculation engine can perform the first operation at the first data source to produce a first result and perform the second operation at the second data source to produce a second result. The calculation engine can then merge the first result and the second result according to a third operation, and perform such third operation at the first data source.
