Configurable Network Computing or CNC is JD Edwards‘s (JDE) client–server proprietary architecture and methodology that implements its highly-scalable enterprise-wide business solutions software that can run on a wide variety of hardware, operating systems (OS) and hardware platforms. Now a division of the Oracle Corporation, Oracle continues to sponsor ongoing development of the JD Edwards Enterprise Resource Planning (ERP) system. While highly flexible, the CNC architecture is proprietary and, as such, it cannot be exported to any other systems. While the CNC architecture’s chief claim to fame, insulation of applications from the underlying database and operating systems, was largely superseded by modern web-based technology, nevertheless CNC technology continues to be at the heart of both JD Edwards’ OneWorld and EnterpriseOne architecture and will play a significant role Oracle’s developing fusion architecture initiative. While a proprietary architecture, CNC is neither an Oracle nor JDE product offering. The term CNC also refers to the systems analysts who install, maintain, manage and enhance this architecture. CNCs are also one of the three technical areas of expertise in the JD Edwards Enterprise Resource Planning ERP which include developer/report writer and functional/business analysts.
