Abstract: The development of wiring data is useful for examining circuitry, finding components and information alternation of equipments during the application of IETM in integrated support. This paper designs the framework of wiring data model and develops its basic functions to improve the efficiently of IETM. The wiring data of use case circuit is formatted into XML according to wiring data schema model. It realizes the call and query of data by XML serialized and deserialized technology. Using the XML special data store technology, XML document is stored in native database; it keeps the integrity of data format. Finally the information of wiring data is shown by combining XSL and CSS.
