Capp Process Data Based On Xml Standards And Applications

The development of network has promoted the construction of enterprise information systems. Simultaneously, enterprise data has begun huger. Process data,which supports CAPP (Computer-Aided Process Planning) system as data layer, is one of the nucleal of enterprise data. New requirements are put forward for the process data in CAPP.NET , a Browser/Service mode CAPP system. This paper deeply discusses the content and structure of process data, establishes a XML(eXtensible Markup Language) process data model, and presents the XML expression of the special process data. Combined with the application of Nanqi CAPP system , some disposal mechanism and methods are proposed on the basis of the XML data model, such as data exchange, data transport, data storage, data query, data security and data integration.At the end of this paper, the realization of several CAPP functional modules are expounded to interpret the disposal details of XML process data.
