| 摘要: |
| 存储管理（特别是辅存管理）是任何一个数据库系统的物理实现层，持久性若不最终落实到辅存上，就是一句空话．本文首先讨论了将程序设计语言和持久对象进行集成的３种途径；然后介绍了ＭＩＤＳ存储管理子系统ＳＭＳ（ＳｔｏｒａｇｅＭａｎａｇｅｍｅｎｔＳｕｂｓｙｓｔｅｍ）的设计：（１）ＳＭＳ的体系结构，（２）ＭＩＤＳ对象的存储结构，（３）对象标识的设计，（４）簇聚与索引，（５）持久性的实现，（６）动态地址转换． |

| Abstract: |
| Storage management, especially second storage management is the physical implementation level for every database system. Persistence is nonsense without adequate support of second storage management. This paper discusses three approaches for integrating programming language and persistent objects firstly, then introduces the design of storage management subsystem (SMS) of MIDS/BUAA, i. e. (1 ) the architecture of SMS, (2) storage structure of MIDS Object, (3) object identity design, (4) objects clustering and indexing, (5) persistence implementation, (6) dynamic UID transformation to memory address. |
| Key words: Storage management, object, object identity, clustering, indexing, persistence. |
