Multiple Continuous Skyline Query Processing Over Data Streams

摘要: Recently, the processing of data streams such as stock quotes, buy-sell orders, and billing records becomes more important in e-Business environments. Especially, use skyline queries over is rapidly increasing to support multiple criteria decision making. Given a set multi-dimensional tuples, query retrieves tuples which are not dominated by other tuples. Although there has been much work on static datasets, relatively less streams. In this paper, we propose an efficient method for continuous The proposed efficiently identifies tuple query, resulting lower cost queries. Through performance evaluation, show advantage method.
