History[02]
Research for GRACE began around 1981 under Masaru Kitsuregawa at the University of Tokyo. The system was designed to address the complexity of conventional join operations by introducing hash clustering. Its architecture featured multiple processing modules equipped with LSI sorters, a memory module, and a disk module, interconnected via dual ring networks. It served as an early academic prototype for parallel database processing.
