数据库重组可以被定义为改变数据库在逻辑上和/或物理上的排列方式的某些方面。一个例子是从一对一关系转变为一对多关系。重组是数据库系统中的一个必要功能。本文介绍了重组的基本概念，包括为什么要进行重组。许多类型的重组被描述并分类为逻辑/物理级别。然后，务实的问题，如重组战略，调查的几个商业重组设施，案例研究，和数据库管理cons~deratmns。最后，一些研究工作进行了调查。
Database reorganization can be defined as changing some aspect of the way in which a database m arranged logically and/or physically. An example is changing from a one-toone to a one-to-many relationship. Reorganizatmn m a necessary function in a database system. This paper introduces the basic concepts of reorganization, including why it is performed. Many types of reorganization are described and classified into logical/physical levels. Then pragmatic issues such as reorganization strategies, a survey of several commercial reorganization facilities, case studies, and database administration cons~deratmns are covered. Finally, several research efforts are surveyed.
