Flash movie is gaining widespread usage nowadays. There are dozen of Flash movies now available throughout the Internet. In order to allow Flash movies to be queried, we create an OXF (Object XML for Flash) model by converting Flash movies into XML format. We apply Structural Join Index Hierarchy (SJIH) indexing technique to enhance retrieval of OXF objects. A detailed cost model for query execution through SJIH is developed. Our experimental studies on using SJIH based on Flash movies has demonstrated performance advantageous when compared with other indexing techniques.
