Computer readable storage medium recording database search program, database search device, and database search method

摘要

In a search device according to the present invention, a path trie generation unit generates an input path trie from XML data, a path trie display unit outputs the input path trie to an output unit such as a display, so that a user can specify Join points and combining conditions. An instruction reception unit generates a query serving as a command statement to combine each piece of XML data based on the Join points and the combining conditions that are specified by the user.
