本章讨论的重点是关于各个组件的介绍和安装，卸载，关于相关组件的使用不在本章讨论的范围内
1、OWR(Oracle Warehouse Builder)
OWB是创建数据仓库的一个过程。Oracle的OWB是目前最好的三大ETL产品之一。
OWB不但可以可以完成数据的抽取、转换和加载，还能帮助用户在Oracle数据库中创建ROLAP(Relational Online Analysis Process)
和MOLAP(Multidimensional Online Analysis Process)数据仓库对象，数据质量管理，商务智能定义等。总之就是ETL工具
Description:
------------
This component will appear in dba_registry when you have configured Warehouse Builder in your database.
Schema:
---------
OWBSYS (This is available from Oracle RDBMS 11gR1 onwards, see below.)
How to Install and De-Install:
------------------------------
Note 340955.1 - Oracle Warehouse Builder, Releases and Patches
See Also: Oracle OWB Documentation
2、APEX(Oracle Application Express)
Oracle Application Express 是一个适用于 Oracle 数据库的快速 Web 应用程序开发工具。
只需要一个 Web 浏览器和有限的编程经验，就可以快速、安全地开发和部署专业的应用程序。
Description:
------------
Oracle Application Express (Oracle APEX) is a rapid web application development tool for the Oracle database.
Using only a web browser and limited programming experience, you can develop and deploy professional applications that are both fast and secure.
Oracle APEX is a fully supported, no cost option of the Oracle database.
The APEX product requires a database in which to install the APEX database packages, procedures, functions, tables, etc. and an HTTP Server which is used to call the APEX application from a browser.
APEX is currently supported on on 10.1 and higher. The 11.x version of the database automatically installs Application Express by default.
Schema:
---------
APEX_xxxxxx
How to Install and De-Install:
------------------------------

3、EM(Oracle Enterprise Manager)
在安装 Oracle 软件时，Oracle Universal Installer可以选装Oracle Enterprise Manager。
Enterprise Manager 提供了一个基于 Web 的界面，可以使用这个界面来管理 Oracle 实例和数据库。就是取代SQLPLUS管理数据库的一个工具，事实上也取代不了。
Description:
------------
This component will appear in dba_registry when you have configured a db console in your database. This is available from Oracle rdbms 10gR1 onwards.
Please note that for this component you need to have Oracle Enterprise Manager installed at binaries level.
Schema:
---------
DBSNMP, SYSMAN, MGMT_VIEW (11gR1 and 11gR2 only)
How to Install and De-Install:
------------------------------
Note.278100.1 How To Drop, Create And Recreate DB Control In A 10g Database
(This note is applicable to 11gR1 and 11gR2)
Please note that reconfiguring the dbconsole will remove the existing settings in dbconsole. So after dropping and recreating the em repository you need to redo all the em related setting.
4、OLAP Catalog, OLAP Analytic Workspace, Oracle OLAP API
这里的三个组件都是Oracle OLAP的核心组件。Oracle OLAP是Oracle企业版的一个可选件，由于将OLAP引擎完全集成进了Oracle数据库，
所以，所有数据和元数据都是从Oracle数据库内部进行存储和管理的，以提供高度可伸缩性、强健的管理环境及工业级可用性和安全性。
Oracle OLAP主要包括以下组件：OLAP Analytic Workspace，用于分析工作区中实际存储多维模型的数据。一个Analytic Workspace存储为一个关系表，
分析工作区中的不同对象存储为表中的一行(LOB格式)。分析工作区甚至可以存储在分区表中，以提供更好的并发性能。
OLAP API 是Oracle OLAP的一个Java编程接口，支持OracleBI Bean。除了服务器组件，Oracle OLAP还提供了两个客户端工具：
支持版本(9i,10gR1,10gR2,11gR1,11gR2)
Description:
------------
Introduced in 9i, OLAP applications are developed within the context of business intelligence and data warehousing systems,
and the features of the OLAP API are optimized for this type of application. With the OLAP API, a Java application can access,
manipulate, and display data in multidimensional terms. The OLAP API also makes it possible to define a query in a step-by-step process
that allows for undoing individual query steps without reproducing the entire query. Such multistep queries are easy to modify and refine dynamically.
The OLAP API is a Java application programming interface (API) through which an application can access data for online analytical processing (OLAP).
The Java classes that implement the API are part of the Oracle OLAP component.
The purpose of the OLAP API is to facilitate the development of OLAP applications, which allow users to dynamically select, aggregate, calculate,
and perform other analytical tasks on data through a graphical user interface. Typically, the user interface of an OLAP application displays data
in multidimensional formats, such as graphs and crosstabs.
The following components must be installed and valid to support the OLAP installation, and should be installed and valid before OLAP is installed:
Component:
JServer JAVA Virtual Machine
Oracle Database Java Packages
Oracle XDK
Oracle XML Database
Schema:
---------
OLAPSYS/MANAGER (9i, 10gR1, 10gR2, 11gR1,11gR2)
The account used to create OLAP metadata structures. This account owns the OLAP Catalog.
The OLAP catalog is created in CWMLite tablespace in 9i but in 10g it is SYSAUX tablespace.
