Abstract

There are countless animation movies available nowadays throughout the Internet. Rich media (including Flash and PowerPoint) presentations are increasingly gaining widespread usage, particularly in the domains of elearning and digital entertainment. In order to allow these animation movies to be queried efficiently, in this article we present OXML - an Object XML database for storing and retrieving animation movies. After converting the movies into XML format, OXML stores the resultant XML data into a native object-oriented database. To enhance the retrieval of such XML objects, an indexing technique known as Structural Join Index Hierarchy (SJIH) is then applied to the OXML database. A detailed cost model for query execution through SJIH is developed. Our experimental studies on accessing Flash movies using SJIH has demonstrated performance advantageous when compared with other indexing techniques. © 2011 ACADEMY PUBLISHER.
