This paper describes MOCHA, a new self-extensible database middleware system designed to interconnect data sources distributed over a computer network. MOCHA is designed to scale to large environments and is based on the idea that some of the user-defined functionality in the system should be deployed by the middleware itself. This is realized by shipping Java code implementing either advanced data types or tailored query operators to remote data sources and have it executed remotely. Optimized query plans push the evaluation of powerful data-reducing operators to the data source sites while executing data-inflating operators near the client's site. The Volume Reduction Factor is a new and more explicit metric introduced in this p...
