一个内存数据库管理系统的数据组织

Data Organization for a Main Memory Database Management System

在分析多种内存数据库概念的基础上，给出了新的内存数据库的形式定义，提出了内存数据库的一种数据组织结构，在Ｔ树的基础上，经过改造开发了一个在自行研制的主动实时ＤＢＭＳ原型系统中实现的索引结构Ｔ树，着重讨论了其严格的定义和操作算法．

A new formal definition for the main memory database is given on the basis of the concepts of multiple memory databases. A data organization structure or the main memory database management system is presented. After reform a new index structure T * tree, based on T tree and realized in the active real time DBMS, prototype system developed by the authors is proposed. Its strict definition and operation algorithm are emphatically discussed.
