Object-oriented DBMS requirements

The requirements on an object-oriented DBMS for management of information in a large, complex enterprise are presented. These requirements aid in the achievement of an environment characterized by data sharing, open architectures, application and data portability, and assurance of data integrity. They were defined from the point of view of a user of the DBMS; therefore they describe the expected functionality of the DBMS and do not specify the method of implementation to achieve this functionality. They encompass requirements on the data model, query and data manipulation languages, the system architecure, interfaces to the system, change management, and transaction management.     

基于多Agent的远程故障诊断系统架构研究

基于Agent及多Agent的概念和技术及其应用系统具有的多方面良好特性,如主动性、智能性、交互性、协作性、移动性等,为研究实现远程故障诊断系统（IRDS）提供了一种崭新的架构思想与方法,这种架构实现有利于保障IRDS的开放性、扩展性及对Internet环境的适应性等方面的特性。     

信息资源词典系统及其服务接口标准

介绍ＩＳＯ／ＩＥＣ在１９９３年制定的ＩＲＤＳ服务接口标准，描述在ＩＲＤ定义级和ＩＲＤ级所要维护的数据结构的定义，以及维护、查询这两级数据的服务。通过服务接口、任何程序都能访问所有的ＩＲＤＳ服务。     

The diffusion of anticipatory standards with particular reference to the ISO/IEC information resource dictionary system framework standard

In the late 1980s, traditional standards development organisations (SDOs) were moving toward creating anticipatory standards as a way of coping with the fast growth in new technology in the computing industry. The development of anticipatory standards (standards developed ahead of the technology) was seen as a possible way for the formal standards bodies to keep abreast of these rapid changes. By creating standards ahead of the technology, the standards would act as “change agents” and guide the market. Anticipatory standards were seen as one way of addressing the problem of arriving at suboptimal de facto standards. If the industry can be guided before the technology develops, this will encourage the use of optimal products. This paper considers the diffusion pattern of the ISO/IEC Information Resource Dictionary System (IRDS) Framework standard that fits into the category of an anticipatory standard. Comparisons are made between the diffusion patterns of the ISO/IEC IRDS standard and the ISO/IEC Open Standards Interconnection (OSI) Reference Model as they were both anticipatory in nature, both framework/reference standards, both originated at approximately the same time and were both developed in traditional standards development organisations.     

仓库技术

仓库技术是支持软件工程集成环境的必要手段之一，也是支持ＣＡＤ／ＣＡＭ等复杂数据处理的重要方法。本文围绕仓库的概念，发展及其实现作了一些讨论，同时，还进一步讨论层次数据库管理系统（ＨＤＢＭＳ），网状数据库管理系统（ＮＤＢＭＳ），关系数据库管理系统（ＲＤＢＭＳ），面向对象的数据库管理系统（ＯＯＤＢＭＳ），知识库管理系统（ＫＢＭＳ）在仓库技术的实现中所扮演的角色。
