Abstract

Atlas is a prototype of an object infrastructure. It is designed to support hundreds of millions of objects, distributed in a heterogeneous wide area network of thousands or millions of computers. Atlas is implemented mainly as a vehicle for experimenting with distributed office and information systems. Atlas supported much finer-granularity objects than traditional client/server networking models. Atlas provides location-transparent method invocation and dynamic creation, deletion, and migration of persistent and non-persistent objects. Iris is an object-oriented database management system, supporting OSQL as its main implementation language. KBMS1 is a knowledge-base management system supporting kbProlog as its implementation language. Both these databases have been integrated with Atlas. The purpose of the integration is to demonstrate that object-oriented technology is appropriate for integration of heterogeneous sources of information and information processing facilities. Atlas objects can be implemented in OSQL and reside in Iris or implemented in kbProlog and reside in KBMS1. Atlas objects can also be implemented in traditional programming language such as C. Objects implemented in any of the two databases or in traditional programming languages can communicate uniformly with each other.<>

数据和知识库是分布式对象基础结构的组成部分

Atlas是对象基础设施的原型。它被设计成支持数以亿计的对象，分布在数千或数百万台计算机组成的异构广域网中。Atlas主要是作为试验分布式办公室和信息系统的工具来实施的。Atlas支持比传统客户机/服务器网络模型更细粒度的对象。Atlas提供了位置透明的方法调用，以及持久性和非持久性对象的动态创建、删除和迁移。Iris是一个面向对象的数据库管理系统，支持OSQL作为其主要的实现语言。KBMS1是一个支持kbProlog作为实现语言的知识库管理系统。这两个数据库都已与Atlas集成。集成的目的是证明面向对象技术适用于异构信息源和信息处理设施的集成。Atlas对象可以在OSQL中实现并驻留在Iris中，也可以在kbProlog中实现并驻留在KBMS1中。Atlas对象也可以用传统的编程语言(如c)实现。在这两种数据库中的任何一种或传统编程语言中实现的对象都可以相互统一通信。
