    摘要: A database system providing methodology for execution of functions in queries requesting data from markup language documents is described. In one embodiment, for example, a method is described for executing a function in a query requesting data from a markup language document stored in a database, the markup language document organized hierarchically into nodes, the method comprises steps of: receiving the query requesting data from the markup language document, the query including a function to be executed during execution of the query; determining nodes of the markup language document satisfying the query; deriving values of the nodes of the markup language document; and executing the function with the derived values and the nodes of the markup language document.

    摘要: A method for loading information into a tree structured database includes receiving a document and forming a top-down tree characterizing the document. Leaf nodes in the top-down tree are identified. Bottom-up indices are formed for the leaf nodes, where the bottom-up indices characterizes paths from selected leaf nodes to a root node of the top-down tree. The top-down tree and bottom-up indices are stored as separately searchable entities in the tree structured database.
