A calculation engine of a database management system is described. In some implementations, the calculation engine receives a calculation scenario including a plurality of calculation views comprising one or more relational operations. The calculation engine determines whether a first calculation view includes a second calculation view configured as an operand of one of the relational operations of the first calculation view, and also determines whether the second calculation view comprises a non-relational operation. The calculation engine further converts the plurality of calculation views into a calculation plan via merging the first calculation view with the second calculation view when the first calculation view is determined to comprise the second calculation view as an operand, and replacing the second calculation view with a view search operation when the second calculation view is determined to comprise the non-relational operation. Related systems, methods, and articles of manufacture are also described.
