In this research, a user need's investigation system is developed based on the technology of automatic translation on XML documents. The aim of our research is to realize the flexibility function to quickly revise data schema of various questionnaires for user need's investigation on Web site. We implement the system by using "XDES", which is a heterogeneous extensible data entry system for XML documents. We apply the XDES to construct some useful function as a part of user need's investigation system on Web site. The main idea of our research is to construct the function of time series version management of the answers for questionnaires by the function of version management of XML documents on XDES. This research is applied to unify the information about the need's of farmers, restaurant managers, and general consumers for the purpose of efficient circulation of agricultural products.
