论题：浅析VFP(传统数据库)与SQL SERVER(网络数据库)

摘　要

数据库是计算机领域发展最快的科技之一，随着数据库规模越来越大，网络越来越普及，传统数据库系统已很难适应飞速增长的性能要求，未来的高性能数据库将是网络数据库系统和并行数据库系统。本文论述了VFP库（传统数据库）和SQL SERVER（网络数据库）之间关系和区别以及各自的特点，如何结合VFP和SQL SERVER来完善老数据库系统，开发基于C/S的网络数据库系统。数据库技术从诞生到现在，在不到半个世纪的时间里，形成了坚实的理论基础、成熟的商业产品和广泛的应用领域，吸引越来越多的研究者加入。数据库的诞生和发展给计算机信息管理带来了一场巨大的革命。三十多年来，国内外已经开发建设了成千上万个数据库，它已成为企业、部门乃至个人日常工作、生产和生活的基础设施。同时，随着应用的扩展与深入，数据库的数量和规模越来越大，数据库的研究领域也已经大大地拓广和深化了。30年间数据库领域获得了三次计算机图灵奖（C.W. Bachman, E.F.Codd, J.Gray），更加充分地说明了数据库是一个充满活力和创新精神的领域。就让我们沿着历史的轨迹，追溯一下数据库的发展历程。

Abstract

The database is a calculator realm to develop one of quickest science and technologies, along with database scale more and more big, network more and more universal, traditional database system already the very difficult orientation fly to soon increase of function request, the future high performance database will be a network database system with proceed together database system.This text discussed a VFP database(traditional database) SQLSERVER(network database) it a relation and distinguish and respectively of characteristics, how combine VFP and SQL SERVER to come to perfect and old database system, development according to thenetwork database of the C/S system. Database technology from birth to now, less than half a century, forming a solid theoretical Basis, mature and widely used commercial products leading Field, attracting more and more researchers to join. Database The birth and development to bring the computer information management A huge revolution. 30 years, at home and abroad have The development and construction of thousands of databases, it has An enterprise, departmental and even personal daily work, production And the life of infrastructure. Meanwhile, with the application of expansion Development and in-depth, volume and size of the database more Large database of research has also been greatly expanded Wide and deepened. Database in the field 30 years received Three computer Turing Award (C. W. Bachman, E. F. Codd, J. Gray), to more fully explain The database is a dynamic and innovative Area. Let us follow the path of history, tracing a Under the database development process.
