3. Objectives & Audience
Objectives
• Introduction to OBIEE
• Installation Basics
• Demonstrate a simple repository creation
• Demonstrate OBIEE Answer Requests and Dashboards
Audience
• Oracle Reports Developers with no OBIEE exposure
• Oracle Discoverer Administrators and Developers with no OBIEE exposure
• Traditional Oracle Report Users
4. Introduction to OBIEE
• It is a query tool
• Unlike simple reporting tool, it allows users to carryout Analysis
• It has far more rich features than Discoverer
• It is completely web based design
• It has an impressive common sense, intuitive user interface, very easy to learn
• It came with Siebel acquisition, Siebel got it from nQuire Software in 2001, it was
designed to be database/Applications vendor independent
• It is a myth to assume OBIEE can improve performance, improving performance
depends on optimal Data Source Schema design and accurate Metadata setup in the
repository
5. Architecture
• Clients
– Oracle BI Answers to build Requests (Reports)
– BI Dashboards to Display results of the Answers Requests
– BI Administration Tool to build repository
• Oracle BI Presentation Services
– Renders pages
– Extension to Web Server
– Users a catalog folder to store user content
– Acts as an intermediary, receives data from Oracle BI server and provides it to
the client
• Oracle BI Server
– Uses the RPD file (metadata) to form dynamic SQL
– It can connect natively (Oracle OCI) or through ODBC to the RDBMS
– It Structures the results set
• Data Sources
– Relational Database, OLAP databases, Flat Files, Spreadsheets, XML files
6. Some of the Other Components
• Oracle BI Scheduler
– Just like Concurrent Manager, it schedules Answers Requests, Scripts,
Alerts
• Oracle BI Delivers
– Few Web pages that allows us create alerts based on Answers
Requests
– IBOTS (OBIEE provides few web pages that allows us to create alert
setups)
– It works with the Scheduled
• BI Administration tool to manage Analytics Metadata RPD files
– (Windows Based only)
7. Sample Request Processing
1. Users views a dashboard or submits a request via
Answers
2. Oracle BI Presentation Services makes a request to
Oracle BI Server to retrieve the requested data
3. Using the repository file, Oracle BI Server optimizes
functions to request the data from the data sources
4. Oracle BI Server receives the data from the data
sources and processes as necessary
5. Oracle BI Server passes the data to Oracle BI
Presentation Services
6. Oracle BI Presentation Services formats the data and
sends it to the client
8. Install Options
• It can run on both Windows and Linux
• You can deploy all server based components in one server or in multiple
servers (with cluster configurations)
• Basic Install does not require a separate Applications Server, Advanced
Install do.
• Basic Install is available only on Windows and it is very easy to install
• There are some tools such as BI Administration Tool that are windows
based only
