Abstract: A new model description was proposed which is divided into heavy and light model for reducing the pressure of the network transfer which is constructed by XML files. The model description includes the production assembly tree information, part feature information and geometry information. So it can satisfy the request of browse, query, and annotation with the model. At the same time, model description is compressed by several methods which avoid the designers from the long time waiting.

Abstract: The technique of collaborative design and manufacture is not only very important, but also urgent necessary for space antenna. Building on unicode, XML provides the standard format describing data in various types, so it has the virtue of integrating heterogeneous databases. In this paper, the elementary research has been done on XML-based integrating technique for heterogeneous databases of space antenna. Firstly, the overall flow for collaborative design and manufacture of space antenna shows that five databases should be integrated. Secondly, a XML-based integration system frame is conceived for space antenna databases. Thirdly, an effective XML-based transformation mechanism is proposed for the data integration process between relational database and document-based database. Finally, the implement of XML-based database integration is demonstrated in a space antenna design.
