Abstract:

Building egovernment needs information from mass distributed agent points. The information comes from different MIS systems which are heterogeneous. It is a hot topic how to receive information efficiently realtime and communicate between centre and agents dynamically. An integration method of heterogeneous data in egovernment is introduced which stipulates a message answer mechanism. Data structure and content of message/answer are defined. The method is a selfadaptive technology which can test and modeling data structure automatically and based on distribution, obtain, transform, coordination and usage of entropy of information in P2P network.

Key words: heterogeneous data, integration, message, dictionary table, code switch table
