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.

Reliability, Flexibility and Performance
Due to the extensive testing all NAG routines are subject to, users can implicitly trust their reliability and accuracy. Additionally, accompanying all NAG routines is comprehensive and detailed documentation. Users subscribing to NAG's support service gain access, via the NAG response centre to the experts who create the routines. NAG routines can be called from many diverse environments including Excel, VB, C, C++, .NET (C#, F#), Delphi for .NET and Java. It is available with support for all main stream architectiures Microsoft Windows, Linux, Solaris and AIX.
NAG offers a bespoke custom engineering program, outsourcing expertise for special projects. This service can help speed crucial development time and reduce costly resource on dedicated in-house engineers.
