Abstract
Business needs have driven the development of commercial database systems since their inception. As a result, there has been a strong focus on supporting many users, minimizing the potential corruption or loss of data, and maximizing performance metrics such as transactions-per-second and benchmark results [Gra93]. These goals have little to do with supporting business intelligence needs such as the decision support and data mining activities common in on-line analytic processing (OLAP) applications. As a result, business data are typically off-loaded to secondary systems before these activities occur. In addition, they have little to do with the needs of the scientific community, which typically revolve around a great deal of compute and I/O intensive analysis, often over large data with high dimensionality. For scientific data, in many cases the data was never collected in a DBMS in the first place, and so the analysis and visualization take place over specialized flat-file formats. This is a painful solution, because a DBMS has much to offer in the overall process of managing and exploring data.
