摘要
A method receives a query containing at least a statement, and analyzes the statement to determine a query structure of elements forming the statement. The text of the statement is formatted to reflect the query structure. The formatted text is replaced with an equivalent tree of logical blocs representing the statement in a higher level. The representation of one or more of the logical blocks is shortened. A data flow tree of macro operation nodes is generated based on the logical blocks for presentation to a user.
