摘要 针对面向对象数据库(OODB)的存储管理进行研究,依照ODMG3.0标准,并以Java绑定方式提供实现方案。通过对典型对象存储结构的研究,给出一种兼顾各种类型数据特点的分层对象存储结构。结合这里使用的体系结构,给出一种基于分槽页结构的改进文件存储结构,将存储单位由页面替换成数据库文件。分析OODB中引入的索引,给出一种基于B+-Tree,结合继承层次和聚集层次的综合索引策略。 The paper studies the storage management for object-oriented database, and a new scheme based on the ODMG3.0 standard, is presented by Java binding. By studying the typical storage structure of persistent objects, it proposes a layered storage structure that takes into account the characteristics of diversified data type. Combining with the architecture here, it transforms a file structure based on Slotted-Page Slrueture, substituting storage unit from page to database file. After analyzing the inlroduced indexes for OODB, the paper presents a uniform indexing scheme, based on a B＋-Tree and with both the inheritance and the aggreation hierarchy.
