Critical to business performance is intelligent, informed decision making. Business Intelligence and analytical applications have evolved to become the single most important element of an organisations software remit. Fundamental to business intelligence systems is the underlying numerical code which undertakes the complex computation, analytics, interpretation and result reporting.
