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 该模型通过获取远程数据库的结构映象，使得用户可以在本地定制源、目标数据库表之间的映射关系。同时，将定制的映射关系转化为适合网络传输的xml格式，输送到远程服务器。
