Abstract
The method for help in optimizing a query (10) in a window (24) of a screen of a work station consists of forming a tree (26) representative of the execution plan of the query, representing the tree on the screen (25), making a syntactical analysis of the query in order to form a syntactical graph, comparing the elements of the tree with those of the graph, and completing the tree with elements contained only in the graph. The advantageous result is a method of syntactical analysis consisting of analyzing the function of the RDBMS in order to determine in particular the types of nodes of the syntactical graph and preferably the information associated with these type of nodes.
