Efficient Aggregation Algorithms on XML Stream
XML数据流上的高效聚集算法

Each element and value in a XML stream can be accessed only one time.In this paper,efficient algorithms are proposed for processing aggregation on XML streams.These algorithms efficiently support the processing of the aggregation queries with complex structures and the aggregation queries on XML stream with recursion structures.Theoretical analysis and experimental results show that the proposed algorithms are able to process aggregation queries effectively and efficiently on XML stream with high scalability.
