Foil 50 TPC-D - a Decision Support Benchmark?
Overall Evaluation

From Second Part of RDBMS Discussion ARL Database Tutorial -- February 98. by Gang Cheng Marek Podgorny Chao-Wei Ou


TPC-D design contains flaws that make its use questionable even for sequential database systems
Given the complexity of the parallel database systems, attempts to reduce their performance estimate to one number are most likely futile
TPC-D defines no metrics useful for understanding behavior of parallel RDBMSes. TPC-D designers should re-examine academic research work pertinent to the field
Future research work towards definition of DS benchmark for parallel databases seems important
