/spl tau/-Synopses: a system for run-time management of remote synopses

Data synopses are concise representations of data sets, which enable effective processing of approximate queries to the data sets. The /spl tau/-Synopses system was designed to provide a run-time environment for remote execution of various synopses. The /spl tau/-Synopses system has the following key features: multiple synopses, pluggable integration, remote execution, managed synopses, workload support, research platform. The system modules were implemented with remote modules communicating through the .NET Remoting framework.
