Increasingly, powerful and inexpensive computers are situated near individual users, and these computers are linked together either locally or across long distances. The computers are heterogeneous because users require different capabilities; legislating the use of identical systems in any organization seems as unlikely in the future as it has been in the past. Together with parallel processing, heterogenity and distribution are likely to be the dominant characteristics of computer systems during the next decade. The advent of distributed, heterogeneous systems has led to some new problems. One particularly important problem is the lack of support for sharing of programs and data in a safe and convenient manner across a heterogeneous network. This project is aimed at correcting this problem by providing a language-independent object repository. The repository can be used by programs written in different programming languages, and running on different hardware and under different operating systems, to share information. The new repository will be language independent, will store typed, structured objects, will support atomic transactions, will be both highly reliable and highly available, will control access to its objects, will perform well, and will be scalable, so that it can support a wide range of system sizes.

越来越多的强大而廉价的计算机位于附近 个人用户，这些计算机连接在一起， 本地或远距离。 这些计算机是异构的 因为用户需要不同的功能;立法使用 在任何组织中使用完全相同的系统似乎在未来都是不可能的 就像过去一样。 与并行处理一起， 异质性和分布性可能占主导地位 计算机系统在未来十年的特点。 分布式异构系统的出现带来了一些新的 问题 一个特别重要的问题是缺乏支持 以安全和方便的方式共享程序和数据， 异构网络。 该项目旨在纠正这一点 通过提供独立于语言的对象存储库来解决问题。 的 存储库可以被用不同编程语言编写的程序使用 语言，并运行在不同的硬件和不同的 操作系统，共享信息。 新的存储库将是 语言独立，将存储类型化，结构化的对象，将 支持原子交易，将是高度可靠和高度 可用，将控制对其对象的访问，将执行良好， 将是可扩展的，因此它可以支持各种系统大小。
