分布武内存数据库已经成为了当今数据库的研究热点,而索引能够极大地提高数据库操作的性能.T-树索引是数据库系统中广泛使用索引技术之一.在T-树的基础上设计一种新的索引结构,在处理区间查询操作时其效率有明显的提高,也能够很好地解决数据插入、删除操作所造成的数据溢出问题.%Distributed memory database has been the hotly studied topic in present database system. Indexes can greatly speed up the performance of database operation. T-tree index is one of the wildly used indexing technologies in database system.
