Mvc分层模型提供了抽取控制逻辑组件和业务逻辑、数据逻辑组件的理论基础， uml可以从系统的分析和设计建立组件化应用的模型，并采用不同工具分别描述控制逻辑组件和业务逻辑、数据逻辑组件，而servlet 、 jsp 、 ejb提供了实现相关组件的手段。 - Distributed database technology is the integration of database technology and computer network technology . apart from the characteristics of centralized database such as data logical independence and physical independence , it has its own unique characteristics such as distributed independence of data . it has to consider not only the self - government of local places , but also the logical integrity of the whole database
分布式数据库技术是数据库技术和计算机网络技术的结合，它除了具有集中式数据库所具有的特点外，还具有它自己独有的特点：它不但要考虑局部场地的自治，而且要解决全局数据库的逻辑整体性；它除了具有集中式数据库所具有的数据逻辑独立性和物理独立性，还具有数据的分布独立性。
