Aiming at the special material equipment, a multi-layer database structure was studied. The data characteristics, the intrinsic relationship of each layer, and the multi-layer database structure related to the material trademark and its performance were defined. The logical organization and the physical structure of the material series database and the material performance database were designed, as well as the software system was developed based on the Oracle and the J2EE technology. The data exchange between the two databases of the material trademark and the performance can be seamlessly connected, which shows that the system can effectively manage and intuitionisticly display the?material series framework and detail information with text, picture, forms and so on.
