摘要 以对象形式存在的数据与以关系存在的数据库之间,一直存在阻抗不匹配的问题。对象数据会受到系统断开的限制,难以长时间的存储,阻碍了对象模型理论的推广应用。映射技术的出现,很好地解决了对象数据模型与关系数据库模型之间难以兼容的矛盾。对象与关系之间的映射技术,就是通过建立应用程序和数据存储之间的一个持久层,可以自动地把软件设计中的对象持久地转化到关系数据库中,有效地解决了对象数据与关系软件之间的矛盾,实现数据库稳定安全地存储与访问。 There is a mismatch between the object data and relation data, which leads to the issue that the object data can not be stored for a long time. Also, the Theory of Object Model can not be further applied due to the limitations of system halt. The mapping technology is able to solve the mismatch problem between the Object Data Model and the Relation Data Model. The mapping technology between object and relation can set up a persistence layer between the application program and the data, which automatically transfers the objects in the software into the relation database. It can also resolve the mismatch problem between the object data and relation software, which ensures secure storage of and access to the database.
