Design And Implementation Of Document Management Subsystem In Collaborative Office System

With the construction of e-government being propelled to the grassroots, its importance in county and town level is appeared. Because most counties and towns have no governmental networks, how to implement the secure electronic file transmission on the basis of how to make use of the public network connection has become the subject that is must researched by current construction of e-government in grassroots.In this paper, the connotation and extension of the concept of e-government and the relationship between cooperative work platform and document management subsystem are first analyzed and the background and network fundamentals of this document management subsystem are described in details, so as to illustrate that this system must be established on the basis of public network communication. Then, this paper overviews the design of this document management subsystem, deciding to solve the problem of security of communication by cryptographic technique and adapt XML language to solve the problem of the standard of e-document, taking handwriting-signing process to solve the problem of people's use-habit. After that, this paper puts an emphasis on designing the document management subsystem, the XML-based electronic document format and each module of the document management subsystem, adopting E-R model to design for the structure of database, analyzing and designing the database table and the system's security. At last, the application of the document management subsystem is introduced.
