In the context of electronic management, without active technical means for fidelity, confidentiality and preservation, electronic document will lose its true evidence and readability, and even disappear forever. Furthermore, since computer archive management in China is about four years earlier than office automation, the key to E-document archiving is the connection between the two systems. The essence of the interface is to solve the problem of data conversion and data exchange between heterogeneous databases. In view of this, this paper discusses the design and realization of the model of electronic document archiving interface, whose core components are designed to solve two problems: the two-way conversion between relational databases and XML documents and the distributive information transmission based on JMS.
