The model we designed enables users to customize data structure mapping between source database and target database in local machine through getting the structure image of source database and transports it to remote server before converting it to xml formatted which is better for internet transportation 該模型通過獲取遠程數據庫的結構映象,使得用戶可以在本地定制源、目標數據庫表之間的映射關系。同時,將定制的映射關系轉化為適合網絡傳輸的xml格式,輸送到遠程服務器。
