A Novel Mixed Index Strategy for Real-Time Update

In this article, a novel mixed index strategy for real-time update is presented. The strategy combines the inverted file with a structure index and implements the retrieval of both context and structure in an XML collection. It can be effectively used to optimize the query of path expression, decrease the number of update operations, accelerate the process of real-time update and shorten the response time. At last, the experiment validates our strategy.
