Conquest: CONcurrent QUEries over Space and Time

. The need and opportunity to efficiently find patterns and features in the vast and growing scientific data sets of today is apparent. In this paper, we present an extensible and distributed query processing system --- Conquest (CONcurrent QUEries over Space and Time) which delivers high performance for non-traditional database query applications. Conquest is composed of components: query management subsystem, query execution engine and user-interface subsystem. Both operation and data parallelism are supported. Scientists can arbitrarily introduce their familiar well-known raster and vector geometry data types as well as particular algorithms for specific applications. Tools are available to help support new data types and operators so that developers can focus on programming their core logic of algorithms without paying a penalty to deal with the novel execution environment's features. 1 Introduction With the vastly growing availability of satellite raster data sets, either from c..
