Foil 18 Remarks on CPS713 Case Study III) Topic C: Parallel and Distributed Databases

From Case Studies of Computational Science -- Overview of Initial Information Area Applications CPSP713 (714 Prototype) -- Autumn Semester 1994. by Geoffrey C. Fox * See also color IMAGE
NPAC has unusually good expertise in this area with the availability of Parallel Oracle (the largest commercial relational database) and parallel DB2 (IBM's relatively new relational database)
Note that industry standard access language is SQL
  • SQL is naturally parallel and so once parallel database implemented, applications can be parallelized without major attention to nature -- parallel or sequential -- of host machine.
  • Compare with Fortran where we produce a parallel (High Performance Fortran) Compiler but then every use of HPF must still worry about parallel algorithm and parallel code.
Academia is studying Object oriented databases which have attractive features but currently one expects relational databases to dominate parallel database field.
