OverviewDatabase system performance is directly related to the efficiency of the system at storing data on primary storage (e.g., disk) and moving it into CPU registers for processing.Data transfer costs from storage are often the major performance bot..

OverviewMany problems of MonetDB were addressed by a new system, developed in the same research group at CWI, called VectorWise.The main innocatio in VectorWise is its vectorized execution model which strikes a balance between full materialization of i..

OverviewMonetDB is designed from scratch focusing on handling analytical workloads efficiently on modern hardware.Column-at-a-timeMonetDB stores data one column-at-a-time both in memory and on disk and exploits bulk processing and late materializati..
