Abstract: The embedded database is a new database technology. It was created along with the development of Web technology, business intelligent technology and mobile computing technology. The reason why data mining system used embedded database was analyzed. Derby database was made into a separate Eclipse plug-in unit and the unit was applied to data mining system in order to meet the specific needs. The application of embedded database used in data mining system not only addresses the data management issues, but also ensures the portability of the system.

摘要： 嵌入式数据库是伴随着Web技术、商业智能技术和移动计算技术的发展而产生的一种新型数据库技术。分析了数据挖掘系统中采用嵌入式数据库的原因，将Derby嵌入式数据库制作成独立的Eclipse插件，并将其应用于数据挖掘系统，以满足数据挖掘系统的特定需求。嵌入式数据库在数据挖掘系统中的应用，既解决了数据挖掘系统中的数据管理问题，同时又保证了系统良好的可移植性。
