along with the development of the computer technology, we massively use the relational database to manage our informations, and we control these informations with the application program . now, the object-oriented technology is widely used by the programmers . because the relational database and the object are two kind of completely different technologies, the application programs mismatch the relational database . in order to solving the problem as far as possible, the programmers develop a new technology, which is the object-relation database mapping ( o-r mapping ) 目前随着计算机信息技术的发展,我们大量地使用关系数据库来管理我们的相关信息,在管理这些信息的过程中,由于关系数据库本身的专业性,使得信息管理人员不可能直接去操纵数据库,我们必须针对用户的需要开发数据库应用程序。随着对象技术的普遍使用,应用程序现在基本上都是使用面向对象的语言进行开发。
as long as the remote server offers the corresponding data extraction and importation service, the whole process will accomplish . i believe that my thesis will have some value for the future research on the new model of databases mapping mechanism and provide certain deployment value and application significance for web service 本文的工作将有助于领域应用人员通过internet有效的使用远程高性能资源,方便地构造应用系统来解决特定领域问题,同时对于webservice技术在水利领域中的具体实施具有一定的参考价值。
