POTENTIAL: A Highly Adaptive Core of Parallel Database System

摘要

POTENTIAL is a virtual database machine based on general com- puting platforms, especially parallel computing platforms. It provides a complete solution to high-performance database systems by a 'virtual processor +virtual data bus + virtual memory' architecture. Virtual processors manage all CPU resources in the system, on which various operations are running. Virtual data bus is responsible for the management of data. transmission between associated operations, which forms the hinges of the entire system. Virtual memory provides efficient data storage and buffering mechanisms that conform to data reference behaviors in database sys- tems. The architecture of POTENTIAL is very clear and has many good features, including high efficiency, high scalability, high extensibility, high portability, etc.
