SystemX & DBLEARN: Easily Getting More from Your Relational Database

Two systems developed in the Centre for Systems Science at Simon Fraser University over the past several years are described briefly. These systems permit easy ad hoc access to information in databases, often stored implicitly, for decision-makers. We argue for their relevance and utility and explain their architectural characteristics, providing pointers to appropriate references for specific theoretical and operational details. Examples are given to illustrate the power and usefulness of these systems and these examples are drawn from actual databases in use with Rogers Cablesystems Ltd. and the Natural Sciences and Engineering Research Council of Canada NSERC.
