组件式三层嵌入式数据库模型研究

近年来，随着移动设备设计制造技术和无线通信技术的发展，使得移动计算得到了大规模的应用。在进行移动计算应用开发过程中，嵌入式数据库的设计是一个关键环节，同时它也会遇到很多条件的限制。嵌入式数据库的设计需要在高效性，可移植性，可配置性，可扩展性等方面进行考虑。文章分析了目前数据库产品的设计特点，并针对嵌入式数据库的特点提出了一个组件式的三层设计模型。

The study of embedded database based on three lays components model

In recent years, with the development mobile equipment design and manufacturing technology and wireless communications technology, mobile computing has been applied in large-scale. It will meet many restriction when develop the mobile computing application. Therefore, a key component of mobile computing, embedded database will be considered in the design of high-efficiency, portability, configuration and the extension issue. The paper analyses the characteristic of current database products, and gives a three-tier embedded database model based on components.
