Abstract: Heterogeneous data sharing is always a bottleneck problem for the development of collaborative design. The method of STEP/XML element mapping achieves the data transformation between STEP and XML by establishing the mapping relationship of the two data. It’s hard to ensure all element mapping one to one and easy to cause the partial data loss. Based on the research, this paper put forward a new method with data encapsulation. It encapsulates the whole STEP data into the XML data by using of the XML character data, and then the data are uploaded to the collaborative design platform. Another designer can download it and get the original STEP data by using the XML parser. This method is not only easy to be realized, but also can ensure the integrity of the product model data conversion. It is more conducive to achieve collaborative design.

Abstract: We design a small supermarket purchase-sell-stock management system. The system uses Microsoft Visual Basic 6.0 and Microsoft Access 2003 as development tools, uses the object-oriented program design method, data model is housed in a class, which improves the data safety in operation; in addition, the system uses the multilayer structure design patterns, which has powerful advantage in module independence and code reuse. The system can satisfy daily job requirement for a small supermarket.
