Oracle Database Documentation Roadmap
Oracle数据库文档路径图
This section explains how this manual should be read and where it fits into the Oracle
Database documentation set as a whole.
这一部分介绍了如何阅读该手册,以及文档内容分类。
To a new user, the Oracle Database documentation library can seem daunting. Not only are there are over 175 manuals, but many of these manuals are several hundred pages long. However, the documentation is designed with specific access paths to ensure that users are able to find the information they need as efficiently as possible.
对于新手来说，Oracle数据库文档库似乎混杂无续。不仅手册繁多，多大175个，而且很多手册都有几百页。尽管如此，这些文档都设计有具体访问路径，以保证用户可以尽可能搞笑的查找到需要的信息。
The documentation set is divided into three layers or groups: basic, intermediate, and
advanced. Users begin with the manuals in the basic group (Oracle Database 2 Day DBA, Oracle Database 2 Day Developer's Guide, or this manual), proceed to the manuals in the intermediate group (the 2 Day + series), and finally to the advanced manuals, which include the remainder of the documentation set.
文档集被划分为了3个层次或等级：初级、中级和高级。使用者可以从初级手册入手(Oracle Database 2 Day DBA, Oracle Database 2 Day Developer's Guide, 等等)，然后是中级(the 2 Day + 系列)，最后到高级，这个过程暗含在了文档集的划分上。
Basic Group
基础文档
Technical users who are new to Oracle Database begin by reading one or more manuals in the basic group from cover to cover. Each manual in this group is designed to be read in two days. In addition to this manual, the basic group includes:
刚接触Oracle数据库的技术人员可以从初级组手册入手。组内的每一个文档都被设计为两天的阅读量。除了该文档（Database Concepts），还包括：
■Oracle Database 2 Day DBA
This manual is a task-based DBA quick start that teaches you how to perform day-to-day database administrative tasks. It teaches you how to perform all common administrative tasks needed to keep the database operational, including how to perform basic troubleshooting and performance monitoring activities.
该文档是基于任务的，通过此文档，DBA可以快速学会如何完成数据库日常管理任务，并教你如何完成必要的日常任务以保证数据库的可用性，包括如何完成基本的排错和性能监控。
■Oracle Database 2 Day Developer's Guide
This manual is a task-based database developer quick start guide that explains how to use the basic features of Oracle Database through SQL and PL/SQL.The manuals in the basic group are closely related, which is reflected in the number of cross-references. For example, Oracle Database Concepts frequently sends users to a 2 Day manual to learn how to perform a task based on a concept. The 2 Day manuals frequently references Oracle Database Concepts for conceptual background about a task.
该文档是基于任务行文的，开发人员快速阅读指南可以了解借助SQL和PL\SQL如何使用Oracle数据库基础特性。基础文档之间联系紧密，相互参考。例如，Oracle数据库相关概念频繁指引用户参考2 Day手册。2 Day文档也频繁参考Oracle数据库相关概念。
Intermediate Group
中级文档
The next step up from the basic group is the intermediate group. The manuals in this
group are prefixed with the word 2 Day + because they expand on and assume information contained in the 2 Day manuals. These manuals cover topics in more depth than was possible in the basic manuals, or cover topics of special interest. As shown in Table 1–1, the 2 Day + manuals are divided into manuals for DBAs and developers.
学习了基础文档，下一步就是学习中级文档。这类文档的命名都带有2 Day +前缀关键字，因为这些文档是基础文档的扩展。与基础文档相比，这类文档涵盖的主题较深入，或者涵盖了一些特殊主题。如表1-1所示，2 Day +手册按管理员和开发者划分为两类。
Advanced Group
高级文档
The next step up from the intermediate group is the advanced group. These manuals are intended for expert users who require more detailed information about a particular topic than can be provided by the 2 Day + manuals. Essential reference manuals in the advanced group include:
学习了基础文档，下一级别就是学习高级文档。这类文档是面向专家级用户的，他们通常需要获取一些特殊主体的更多细节信息。在高级文档中，必不可少的手册包括：
■Oracle Database SQL Language Reference
Oracle数据库SQL语言参考手册
This manual is the definitive source of information about Oracle SQL.
该手册是关于Oracle SQL的权威性资料。
■Oracle Database Reference
Oracle数据库参考手册
The manual is the definitive source of information about initialization parameters,data dictionary views, and dynamic performance views.The advanced guides are too numerous to list in this section. Table 1–2 lists guides that are used by the majority of expert DBAs and developers at one time or another.
该手册是关于数据库初始化参数，数据字典视图，动态性能视图的权威性资料。在一部分，高级指南成员众多，不胜枚举。表1-2列出了一些指南，专家级管理员和开发者通常会用到这些指南。
Other advanced guides required by a particular user depend on the area of responsibility of this user. For example, a security officer will naturally refer to the Oracle Database Security Guide.
按照用户工作职责，一些特殊用户可能会用到其他高级指南。例如，安全管理员理所当然的会参考Oracle数据库安全性指南。
