OBIEE Overview


Oracle Business Intelligence Suite Enterprise Edition (OBIEE) is an enterprise Business Intelligence platform with the ability to source from multiple heterogeneous data sources to enable pervasive business analytics.  It consists of a broad set of capabilities including ad-hoc query and analysis, interactive dashboards, reporting, proactive intelligence and alerts, mobile analytics, and more.   The Oracle BI Server, the foundation of Oracle BI Suite EE, generates queries optimized for Teradata, appropriately aggregates data and presents the results to users within a familiar web browser via easy to use dashboards and reports.  While the Oracle BI Server also provides powerful analytic calculation functions it also understands when it should leverage the Teradata database for computation if it would yield better performance. 

Oracle has 4 suites of BI tools with similar and confusing names:

1)    OBIEE is often considered to be a single product; however, OBIEE is an integrated suite consisting of several interdependent components. OBIEE stands for Oracle Business Intelligence Suite Enterprise Edition – but the S for Suite is dropped. OBIEE is based on the acquired Siebel Analytics technology.

2)    OBIEE Plus is the same suite as OBIEE but it also includes the acquired Hyperion reporting tools (SQR and IR).

3)    Oracle Business Intelligence Standard Edition One is a suite that has nothing in common with Oracle Business Intelligence Standard Edition (description follows). Oracle Business Intelligence Standard Edition One is a suite designed for the small to medium sized business. It is based on the exact same technology platform as OBIEE.

4)    Oracle Business Intelligence Standard Edition (OBISE) is a suite with completely different components.

This document deals with the first 3 tools listed above.

Oracle Business Intelligence Applications (OBI Apps) is another Oracle product that includes OBIEE as part of the solution.  OBI Apps is an end-to-end solution that takes data from various source systems such as Siebel CRM, Oracle EBS, PeopleSoft, et al, loads it into Teradata and delivers Business Intelligence (BI) content to end-users.   OBI Apps includes pre-defined data integration mappings from the source system, an optimized physical star schema data model for Teradata, as well as pre-defined OBIEE reports and dashboards for end users.  OBI Applications is described in the “Teradata Corporation and Oracle Corporation Strategic Partnership Technical FAQ” available on TKO and the Oracle InfoHub.

Teradata integrates easily with the OBIEE architecture.  As a warehouse, Teradata provides the data and the power to support the business analytics.

Not shown in the diagram below, Oracle BI EE Plus also bundles key Oracle Hyperion reporting products (SQR and IR) for integrated reporting with Oracle Hyperion financial applications.



Oracle Business Intelligence Enterprise Edition components:
·      Oracle BI Server – As the foundation of OBIEE Plus, the Oracle Business Intelligence Server generates queries optimized for each data source, appropriately aggregates them, and presents the results to end users.  A flexible, enterprise metadata layer spans all of the underlying data sources.   
·      Oracle BI Interactive Dashboards – Provides fully interactive collections of analytic content with a rich variety of visualizations.  Running on a Web-based architecture, the dashboards provide users with information filtered and personalized for their identity, function or role based on predefined security rules.
·      Oracle BI Answers – Self-service ad-hoc capabilities allowing end users to easily create charts, pivot tables, reports, and visually appealing dashboards, all of which are fully interactive with drill down capabilities.
·      Oracle BI Delivers – Near real-time, multi-step alert engine can trigger workflows based on business events and notify stakeholders via their preferred medium and channel (email, dashboards, and mobile devices).  This means field sales representatives can receive a short message service alert on their cell phone, warehouse managers get a PDF attachment via e-mail, and financial analysts obtain the report as an Excel spreadsheet saved to their shared corporate file system.
·      Oracle BI Disconnected Analytics – Full business intelligence functionality for the mobile professional, enabling fully interactive dashboards and ad hoc analysis while disconnected from the corporate network.  Intelligent synchronization of relevant data, analytic metadata, dashboards and saved selections occurs once a user reconnects to the enterprise network.
·      Oracle BI Publisher – Pixel-perfect reporting component allows the creation of highly formatted templates, reports, and documents such as checks, government form, and more.  It provides a central architecture for generating and delivering information to employees, customers and business partners – securely and in the right format.
·      Oracle BI for Microsoft Office – Allows users of Microsoft Excel and PowerPoint to access and run Oracle BI reports directly from within these familiar tools. Refreshable reports leverage native Microsoft Office functionality and the scalability and performance of the Oracle BI Server. Reports also reference a consistent and single source of truth as defined in the Oracle BI Server metadata - a critical requirement for pervasive use across the enterprise.
·      Hyperion Web Analysis – Delivers out-of-the-box OLAP analysis, presentation and reporting.  Hyperion Web Analysis take advantage of the many powerful and advanced analytics features provided in Oracle Essbase or other multidimensional sources. 
·      Hyperion Interactive Reporting – Pulls data from operational or analytic sources to create easily comprehensible charts, pivots, and reports. Hyperion Interactive Reporting adds the option of direct access to relational sources without the need to create and access a semantic layer via the Oracle Business Intelligence Server.
·      Hyperion SQR Production Reporting – Generates massive reports within specified time frames and connects to a wide variety of enterprise data sources.
