Processing Complex Aggregate Queries over Data Streams

ABSTRACT Recent years have witnessed an increasing interest in designing algorithms for querying and analyzing streaming data (ie, data that is seen only once in a fixed order) with only limited memory Providing (perhaps approximate) answers to queries over such continuous data streams is a crucial requirement for many application environments; examples include large telecom and IP
