This thesis will use Topic Maps technology adjusting the BOM structure and the way of manipulation, by the way of the changing technology of the data access, it could promote the system process smoothness, and improve the humanization of the user interface and the simplified operation procedure. Solving the problem of ERP BOM and the connection of the peripheral information, and carry on the deeper case study, demand confirm and the user interface, operation mode and operation procedure, carry on planning and design more .And will make the system design and run with the real case. (brief of API function). Finally TOPIC MAPS system that will be designed for a research institute, benefit that may really improve or solve the practical problem is assessed. Describe the detail of using the TOPIC MAPS function in BOM module. Besides solving the existing problem, it could expand the benefit and the vision of the future.
