An advanced database accelerator

The authors report on a research project launched to develop a complete database management system (DBMS) to support emerging applications. They developed a hardware architecture consisting of a general-purpose host computer and the Delta Driven Computer (DDC), a parallel system that plays the role of a relational database accelerator. They also used compilation and I/O reduction to improve the efficiency of the DBMS and proposed a production-rule language that could be compiled into programs with explicit parallelism. The authors present their research objectives, give a general overview of the DDC, and discuss the elements of a complete DBMS.<>
