Oracle BI Server

• Calculation and Data Integration Engine

‣ “Virtual Data Warehouse”

‣ Allows reporting across multiple sources

‣ Data accessed though metadata layer

• Connects to RDBMS and OLAP data

‣ Oracle Database (including Oracle OLAP)

‣ IBM DB2

‣ Microsoft SQL Server

‣ Teradata

‣ Microsoft Analysis Services (OLAP)

‣ SAP BW 'info cubes'

• Security, Summary Management

• Translates incoming “logical SQL”

(9)

Data Access

• Reporting data may be sourced from

multiple databases, applications

‣ Oracle Database (including Oracle OLAP)

‣ IBM DB2

‣ Microsoft SQL Server

‣ Teradata

‣ Microsoft Analysis Services (OLAP)

‣ SAP BW 'info cubes'

‣ SAP, Peoplesoft, Siebel, E-Business Suite

• Oracle BI Server joins this source

data together and presents a logical business model

‣ Facts

‣ Dimensions

(10)

Common Enterprise Information Model

• Enables consistency, security, reuse, flexibility

• Role-based views of the organization

• Single metadata model of the business

• Consistent definition of business measures, metrics, calculations

• Drill paths, summaries, security

• Model once, deploy anywhere

• Across any data source

(11)

Essbase and Oracle Business Intelligence Enterprise Edition

• Essbase is a key part of Oracle’s Business Intelligence Foundation Layer

• Essbase and Hyperion EPM can play several roles in this architecture

‣ As a data source

‣ As a data consumer

‣ As a portal for all Oracle BI

‣ As a MS Office integration point

• Essbase can benefit from Oracle BI

Enterprise Semantic Model

• OBIEE can benefit from Essbase

(12)

Essbase and Oracle BI EE Integration Points

1. Essbase can be a data source for Oracle Business Intelligence Enterprise Edition 2. The OBIEE Semantic Model can be a data source for Essbase cubes

3. SmartSpace can consume both Essbase and OBIEE data sources

4. Hyperion Workspace can host OBIEE Dashboards, Answers, Delivers and Publisher 5. Informatica PowerCenter is the standard ETL tool for Oracle BI Apps and Essbase 6. Oracle Data Integrator is the future ETL tool for both Oracle BI Apps and Essbase

(13)

Essbase Integration with OBIEE 10.1.3.3.2+

• OBIEE can connect to multidimensional as well as relational sources

‣ Microsoft Analysis Services, SAP B/W, now Essbase 9.3.1/11.1

• Import process converts the multidimensional view into a relational view

• Essbase cubes, dimensions, hierarchies converted to a logical relational star schema

• Essbase data can then be combined

with data from sources

• Typically used to bring in budget,

forecast data etc from Essbase into OBIEE logical model

(14)

Essbase > OBIEE Integration Features

• Connection is via the Essbase Client C API

• Essbase-specific MDX is generated by the Oracle BI Server

• EVALUATE function supported for calling Essbase functions

‣ Essbase specific aggregate functions i.e. TopN, BottomN

‣ Member selection based upon UDAs

• OBIEE Time-Series functions are function shipped to Essbase

• Essbase substitution variables supported

• Ragged and unbalanced hierarchies

(15)

Registering an Essbase Cube in OBIEE Step 2

• Enter the server hostname, username and password

• Connects via Essbase C API, requires Essbase Client to be installed on OBIEE Server

• Compatible with Essbase 9.3.1, 11.1(?)

(16)

Registering an Essbase Cube in OBIEE Step 3

• Essbase cube metadata then loaded into the OBIEE Semantic Model physical layer

‣ OBIEE Physical Database = Essbase Server

‣ OBIEE Display Folder = Essbase Application

‣ OBIEE Physical Cube = Essbase Cube

• Essbase multidimensional model turned into a relational model

• Value-based hierarchy converted to level-based hierarchies

(17)

Registering an Essbase Cube in OBIEE Step 4

• OBIEE physical model can then be automatically converted into a logical model

‣ OBIEE automatically generates facts, dimensions, hierarchies

‣ Alternatively, Essbase model can be incorporated into existing logical model containing other (relational) data

(18)

Registering an Essbase Cube in OBIEE Step 5

• View Essbase data in Oracle BI Dashboards, Oracle BI Answers

• Data is now turned into a relational star schema, but with MDX being generated

to retrieve data from Essbase

• Essbase data can now participate in dashboards, cross-data source analysis

‣ Actuals vs. budget

‣ Actuals with forecast

(19)

Converting Value-Based to Level-Based Hierarchies

• Essbase value-based hierarchies are converted into level-based ones for OBIEE based

on maximum depth of hierarchy at the time of import

‣ OBIEE is a relational query tool, requires a column for each drill path level

‣ Can import ragged and unbalanced hierarchies, these will be converted into flattened level-based hierarchies

• Issue comes when the depth of the hierarchy changes

‣ Essbase cube has to be re-imported into physical model and then re-created in the logical and presentation layers

(20)

Demonstration

(21)

Oracle BIEE as an Essbase Studio Data Source

• Essbase Studio can connect to Oracle BI Server as a data source

• Oracle BIEE Presentation Layer Folders appear as databases

• Connects via HTTP rather than ODBC, JDBC

• Brings across tables, columns (not hierarchies)

• Provides access to the data federation &

(22)

OBIEE as a Data Source Considerations

• Data is unlikely to transform naturally into an Essbase cube

‣ Non-unique keys

‣ Presentation layer may not even feature keys

‣ Illegal characters

• Will require key values to be exposed,

then transformed and aliases added

• Currently several manual steps

• Process likely to be automated in future release

(23)

Registering an OBIEE Model in Essbase Studio : Step 1

• Create a new data source in Essbase Studio,

connect to Oracle BI EE via HTTP

• Database names are the presentation

(24)

Registering an OBIEE Model in Essbase Studio : Step 2

• Import table metadata and create Mini Schema model

• Equivalent to the OLAP Model

in Integration Services

(25)

Registering an OBIEE Model in Essbase Studio : Step 3

• Create hierarchies for the dimension objects

(26)

Registering an OBIEE Model in Essbase Studio : Step 4

• Define aliases for the ID columns used for member IDs

• Avoids problem where descriptions are used as member ID but are too long or contain

(27)

Registering an OBIEE Model in Essbase Studio : Step 5

• Generate Cube Schema from selected dimensions

• Equivalent to Integration Services

OLAP Metaoutline

• Make selection from all dimensions and

(28)

Registering an OBIEE Model in Essbase Studio : Step 6

• Transform OBIEE column IDs so that they are unique across dimension and cube

• Uses transform feature, accessible

(29)

Registering an OBIEE Model in Essbase Studio : Step 7

(30)

Registering an OBIEE Model in Essbase Studio : Step 8

(31)

Registering an OBIEE Model in Essbase Studio : Step 9

• View outline and data within Administration Services

• Data is now loaded into the Essbase

database, will refresh as needed

• Database can also be redeployed

to the OBIEE semantic layer to replace original relational data source for logical model

(32)

Demonstration

(33)

Integration of OBIEE Tools into EPM Workspace

• From OBIEE 10.1.3.4 and Hyperion EPM 11.1, OBIEE tools can be embedded in

Hyperion Workspace

• Access all tools through a common UI

‣ Oracle BI Dashboards

‣ Oracle BI Answers

‣ Oracle BI Delivers

(35)

Oracle Smart View and Smart Space Integration

• Smart View and Smart Space 11.1 support OBIEE from releases 10.1.3.3.1 +

• Works through Provider Services, but Provider Services /

Essbase license not required for use

• OBIEE added as a data source, connects via JDBC

• OBIEE content can be viewed within Smart Space gadgets

‣ Oracle BI Answers

‣ Oracle BI Publisher

‣ Oracle BI Delivers

(36)

(37)

ETL Tool Integration

• Essbase and OBIEE share two common ETL tools

‣ Informatica PowerCenter, a.k.a. Essbase Data Integration Management

‣ Oracle Data Integrator, uses custom Knowledge Modules for OBIEE / Essbase load

• ODI likely to be the strategic ETL tool going forward

(38)

Essbase and OBEE in an Oracle BI/DW Architecture

• Essbase will primarily be a data consumer in the Oracle BI/DW architecture, sourcing

data either directly from applications, the Oracle DW or the OBIEE semantic model

• Essbase can also be used a data source for OBIEE, to boost query performance and

(39)

Summary

• With recent releases of Essbase and OBIEE, many integration possibilities are available

• Essbase can be a data source for OBIEE

• OBIEE can be a data source for Essbase

• OBIEE reporting tools can be incorporated into the EPM workspace

• Common ETL tools can be used to load OBIEE, Essbase and the Oracle DW
