  author={Nabil I. Hachem and Chenye Bao and Steve Taylor},
Scienti c databases are usually large, distributed and dynamically changing. We address the problem of e cient processing of queries in scienti c databases, especially in very large numerical databases. Previous work has focused on how to store the database and the design of index structures for the e cient access of data. Recently more and more statistical methods have been used in query optimization. Those methods essentially attempt to approximate the distribution of the attribute values in… CONTINUE READING
