: In an extensible database system, evaluation of a query plan is done in cooperationbetween a collection of operator implementation functions and a component of the DBMS that wecall the query processor. Basically, the query processor constructs an operator tree for the query planand then calls an evaluator function which traverses the tree, calling the operator functions in eachnode. This seemingly simple strategy is complicated by the fact that operator functions must be ableto call for... |
