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.〔(Oracle Fusion Information URL )〕 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. ==The CNC architecture== Oracle is continuing to develop the CNC technology and will incorporate key elements of the CNC technology into its Oracle Fusion project which will pull together technologies from JDE, PeopleSoft and its own application software technologies. In the CNC architecture, a company's JD Edwards (JDE) business software applications run transparently insulated from both the database where the business data is stored as well as from the client computer's underlying operating system and all other intervening JDE business applications servers. In layman's terms, the business programs don't "care" where the data is or which operating system is being used on any of the end user computers. Neither do the applications servers on which business programs run need to directly "know" what database systems are being called on the data end or back end. The CNC architecture keeps track of this through various database tables that point the business applications to the servers that run or execute the business applications and also include database connection tools called database drivers that tell the system also where the database servers are and what specific databases to do lookups, data inserts and data extracts from. Because of the key nature of the underlying architecture, a sound CNC infrastructure is critical to the success of a JD Edwards OneWorld installation or implementation. The back-end databases that are supported include Oracle, Microsoft SQL Server, and IBM DB2 databases. The application server can run on Windows platforms, Unix/Linux, and the IBM System i (formerly known as iSeries and AS/400). The Web server can be IBM WebSphere (on Windows, Unix/Llinux, or System i), or the Oracle Transaction Server.〔http://www.astradyne-uk.com/manuals/ir019510.pdf JD Edwards OneWorld Xe Implementation on IBM iSeries Servers〕 In what has been known traditionally as client–server environments, applications must communicate across a combination of different hardware platforms, operating systems and databases as including. The CNC architecture uses a layer of software, called middleware, which resides between the platform operating system and the JDE business applications. To accomplish this, JDE provides two types of middleware, JDENET Communication Middleware and JDEBASE Database Middleware. The JDEBASE middleware communicates with the database through ODBC, JDBC, or SQL *Net. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Configurable Network Computing」の詳細全文を読む スポンサード リンク
