....of distributed database architectures has focused on allowing the #exible and dynamic placementofquery operators #e.g. selects, joins, aggregates, etc. # at various sites in the network #Jenq et al. 1990; Franklin et al. 1996; Stonebraker et al. 1996; De#loch et al. 1998; Mayr and Seshadri 1999; Rodgriguez Martinez and Roussopoulos 2000#. In such systems, query operators can be placed at sites in a way that minimizes expected communication costs, execution time, or other metrics. These decisions are based in large part on knowledge of which data is located at which sites. When caching is added to such a system, however, a ....
....Drasch provide the #exibilitytochoose among these options. A #exible approach, however, has become increasingly popular in experimental systems such as ORION 2 #Jenq et al. 1990#, KRISYS #De#loch et al. 1998#, Mariposa #Stonebraker et al. 1996#, Predator #Mayr and Seshadri 1999#, and MOCHA #Rodgriguez Martinez and Roussopoulos 2000#, and has been integrated into an extended version of the SHORE storage manager #Carey et al. 1994# as part of the work described here. In the commercial world, SAP R#3 is a prominent example of a system that has a hybridshipping architecture #Buck Emden and Galimow 1996; Kemper et al. 1998#. ....
