Abstract
A method of operating a tree structured database includes receiving a document, forming a top-down tree characterizing the document, generating pre-computed indices characterizing the document, combining subsets of the pre-computed indices to dynamically create a table of information characterizing the document, and resolving a structured query language query against the table to form collected data.
