MOCHA: A Self-Extensible Database Middleware System for Distributed Data Sources
Summary: MOCHA is a self-extensible middleware for distributed data sources that ships user-defined code to remote sites. It introduces Volume Reduction Factor to guide operator placement, enabling data-reducing work at sources and scalable Java-based deployment on Informix/Oracle.
