ses provide accurate approximations for general-purpose summaries of the streaming data distribution (e.g., wavelets). The focus of existing work has typically been on minimizing . of the maintained synopsis — however, to effectively support high-speed data-stream analysis, a crucial practical requi

stinction between the dual notions of a set and a type, both of which are present in a class. Our paper fills this gap by presenting a framework for executing set-theoretic operations on the class construct. The proposed set operations determine both the type description of the derived class as well

ges. Current database systems can represent objects such as these only with difficulty, and often restrict the type of data that can be stored. In response to these shortcomings, object-oriented database systems have been designed specifically to represent complex objects and accommodate user-define

Our formalism captures transformations of all schema components, making it possible to transform uniformly constraints and queries along with structures. In addition, our formalism captures schema transformations between different data mod

criterion for determining the .NNs is the shortest network distance between objects. We first highlight the limitations of the existing approaches, and then propose a cost-effective algorithm, namely the ., to overcome these limitations. Comprehensive experiments are conducted to demonstrate the efficiency of the proposed approach.

erefore, users need not to know the existence and definition of MAV in order to share materialized data. Incremental update of MAV created from single base table is also considered. The application of MAV to data mining is presented to illustrate the use of multivariate and multidimensional OLAP.
