Abstract
A system comprises generation of a parse tree comprising a plurality of query parse nodes, each of the plurality of query parse nodes corresponding to a respective one of a plurality of portions of a script definition, generation of a first intermediate representation tree comprising an intermediate representation node corresponding to a respective one of each of the plurality of query parse nodes, wherein an intermediate representation node represents a logical operation corresponding to the portion of the script definition of the query parse node which corresponds to the intermediate representation node, definition of links between each of the plurality of query parse nodes and its corresponding the intermediate representation node, determination of a second intermediate representation tree, the second intermediate representation tree resulting from an optimizer transformation executed on the first intermediate representation tree, generation of an intermediate representation node corresponding to a transformed first one or more of the intermediate representation nodes of the first intermediate representation tree, definition of links associating the intermediate representation node corresponding to the transformed first one or more of the intermediate representation nodes with the transformed first one or more of the intermediate representation nodes of the first intermediate representation tree, generation of a script execution graph of script execution nodes, each of the script execution nodes corresponding to a second one or more nodes of the second intermediate representation tree, definition of links associating each of the script execution nodes with its corresponding second one or more of the intermediate representation nodes, generation of a graph comprising the plurality of query parse nodes, the intermediate representation nodes, the script execution nodes and the links, and presentation of the graph.
