1 Introduction to the Oracle Databa
1 This chapter provides an overview of the Oracle databa rver. The
topics include:
∙Oracle Databa Architecture
∙Oracle Databa Features

英语论文答辩技巧∙Oracle数据库体系结构
∙Oracle数据库特性
∙Oracle数据库应用开发
2 Oracle Databa Architecture 1.1 Oracle数据库体系结构
3 An Oracle databa is a collection of data treated as a unit. The purpo
三年级英语下册of a databa is to store and retrieve related information. A databa rver is the key to solving the problems of information management. In general, a rver reliably manages a large amount of data in a multiur environment so that many urs can concurrently access the same data. All this is accomplished while delivering high performance. A databa rver also prevents unauthorized access and provides efficient solutions for failure recovery. An Oracle databa is a collection of data treated as a unit. The purpo of a databa is to store and retrieve related information. 数据库服务器是解决信息管理问题的核心组件。大体上说，数据库服务器的作用是可靠地管理多用户环境下
yellow book的大规模数据，使多用户可以并发地访问相同的数据，同时实现系统的高性能。数据库服务器还要阻止未授权的操作，并提供高效的故障恢复解决方案。
4 Oracle Databa is the first databa designed for enterpri grid
美国城市名字computing, the most flexible and cost effective way to manage information and applications. Enterpri grid computing creates large pools of industry-standard, modular storage and rvers. With this architecture, each new system can be rapidly provisioned from the pool of components.
There is no need for peak workloads, becau capacity can be easily added or reallocated from the resource pools as needed. Oracle数据库是第一个为企业网格计算而设计的数据库，她为管理信息和应用提供了灵活、低成本、高效益的方式。企业网格计算把存储及服务能力转化为符合业界标准、模块化的资源池 （resource pool）。在这种体系结构之下，新系统可以从组件化的资源池中组合资源而迅速构成。企业也无需建设尖锋负荷系统 （peak workloads），因为计算能力可以在需要时轻松地从资源池中获得或重新分配。
5 The databa has logical structures and physical structures. Becau the
physical and logical structures are parate, the physical storage of data 数据库具备逻辑结构和物理
结构。因为物理和逻辑结构是分离的，所以数据物理存储的变动不会影响基于逻辑存储结构的应用程序。
can be managed without affecting the access to logical storage structures.

7 Overview of Oracle Grid Architecture 1.1.1 Oracle网格体系结构概述
8 Grid computing is a new IT architecture that produces more resilient and
lower cost enterpri information systems. With grid computing, groups of independent, modular hardware and software components can be connected and rejoined on demand to meet the changing needs of business. 网格是新出现的IT体系结构，它可以提供更有弹性、成本更低的企业信息系统。在网格中，众多独立的、模块化的软硬件组件可以随时地被联接和重组，以满足业务 及业务变化的需要。
9 The grid style of computing aims to solve some common problems with
enterpri IT: the problem of application silos that lead to under utilized, dedicated hardware resources, the problem of monolithic, unwieldy systems that are expensive to maintain and difficult to change, and the problem of fragmented and disintegrated information that cannot be fully exploited by the enterpri as a whole. 网格形式的计算系统是为了解决企业IT中的常见问题：由不同的应用系统独占硬件资源而导致的资源利用率低下；系统过于庞大而导致的难以 改进、维护昂贵；信息过于分散而导致的企业信息难以作为整体充分利用。
10 Benefits of Grid Computing Compared to other models of computing, IT
abbssystems designed and implemented in the grid style deliver higher quality of rvice, lower cost, and greater flexibility. Higher quality of rvice results from having no single point of failure, a robust curity 网格的优势 和其他体系结构相比，基于网格设计、实施的IT系统能够提供更高质量的服务，更低的成本，更大的灵活性。更高质量的服务来源于网格不存在单点脆弱性（single point of failure），健壮的安全基础结构，和基于策略的集中化管理方式。更低成本来源于软硬件资源利用水平的提高和管理、维护成
