Abstract: | POTENTIAL is a virtual database machine based on general computing 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 systems. The architecture of POTENTIAL is very clear and has many good features, including high efficiency, high
scalability, high extensibility, high portability, etc.
