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.
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 for communication and of JDEBASE Database Middleware. The JDEBASE middleware communicates with the database through ODBC, JDBC, or SQL*Net.

Famous quotes containing the word architecture:
“In short, the building becomes a theatrical demonstration of its functional ideal. In this romanticism, High-Tech architecture is, of course, no different in spirit—if totally different in form—from all the romantic architecture of the past.”
—Dan Cruickshank (b. 1949)
