There has been a significant amount of excitement and recent work on column-oriented database systems (“column-stores”). These database systems have been shown to perform more than an order of magnitude better than traditional row-oriented database systems (“row-stores”) on analytical workloads such as those found in data warehouses, decision support, and business intelligence applications. The elevator pitch behind this performance difference is straightforward: column-stores are more I/O efficient for read-only queries since they only have to read from disk (or from memory) those attributes accessed by a query.
