How to abstract objects from entities of real world is one of the keys to object-oriented database system ( OODBS). Implementations of storage, manipulation and management are based on objects in OODBS.

面向对象数据库系统（OODBS）的核心是把现实世界的事物描述为对象，数据存储、操作和管理都以对象为依据。

For the purpose of this article, I'll take both relational databases ( RDBMS) and object-oriented databases ( OODBS) as one unit, rather than separately.

从本文的主旨出发，我把关系数据库（RDBMS）和面向对象数据库（OODBS）放在一起，不单独讨论。

With the development of Object-Oriented technologies, OODBS ( Object-Oriented Database system) has been one of the most ubiquitous and promising research and application fields in recent two decades.

面向对象数据库系统（OODBS）是近二十年来随着面向对象技术的发展而被广泛接受且非常具有前景的研究及应用的领域。

互联网摘选

The complexity in concurrency controls should not degrade the performance of OODBs. That is, concurrency controls in OODBs must keep performance while meeting the database consistency requirements.

并发控制中的复杂性不应该降低OODBS的性能，即是，OODBS的并发控制在满足数据库一致性要求的时候，要保持性能。

The main task of storage subsystem in object oriented database system ( OODBS) is not only to deal with volatile objects, but also to manage and store plenty of shared and permanent objects, that's why OODBS is complicated and different from other system.

面向对象数据库系统（OODBS）中存储子系统的主要任务是管理和存储大量的共享、持久对象，而不仅仅是处理挥发性对象，这也是OODBS区别于其它系统或者说其复杂性所在。

In the past 30 years, the database system has already developed the no relational model, the next generation Object-Relational Database System ( ORDBS), the third generation Object Oriented database system ( OODBS).

经过30年的发展，数据库系统已经历了第一非关系型数据库、第二代关系型数据库（ORDBS）的发展到面向对象数据库系统（OODBS）和各种专业数据库。

Because there are a few OODBs which support the metaclass mechanism, this methodology has limitation to some degree.

但只有少数的OODBs支持元类机制，因此该方法存在一定的局限性。
