The Oracle BI Applications Business Model & Mapping Layer

•The Business Model and Mapping layercontains the complete, integrated logicaldata model for the OBAW

•Divided in to core and application-specificbusiness models

•Coverage of the business model is determined by the products selectedat installation time


Demonstration

The OBIEE Repository, and Pre-built Dashboards & Reports


Oracle BI Applications Architecture


Predefined, Integrated Dimensional Data Warehouse

•Integrated, conformed dimensional data warehouse•Allows modular deployment•Lowest grain of information•Prebuilt aggregates •Deployable on Oracle, MS SQL,

IBM DB/2 and Teradata•History tracking•Indexing


The Oracle BI Applications ETL Process

•Oracle BI Applications comes with a set of pre-defined ETL routines‣Currently written using Informatica, in future also provided via Oracle DI

•Extracts data from Oracle EBS, Peoplesoft, Siebel, SAP•Universal Adapter available for non-supported sources•Controlled and orchestrated using the Oracle Data Warehouse Administration Console


Oracle Data Warehouse Administration Console

•Control panel for running the OBAW load process•ETL packaged into Execution Plans•Tight integration with Informatica•Run jobs, monitor progress•The added value on top of

the OBAW and INFA mappings


Informatica PowerCenter 8.1.1

•Informatica PowerCenter 8.1.1 is a complete ETL toolkit‣Very much like Oracle Warehouse Builder, but applies to all sources and targets‣Uses an ETL “hub” to

process and distribute data•Server supported on Windows,

Unix, Linux•Client is Windows-only•Five Key Informatica Client Tools‣Informatica Designer‣Informatica Workflow Manager‣Informatica Repository Manager‣Informatica Workflow Monitor


Oracle Data Integrator

•A future release of the Oracle BI Applications will support ODI as the ETL tool‣Initially EBS to Oracle only, future releases will support all sources/targets

•Oracle heterogeneous ETL tool•Acquired through Sunopsis Acquisition•ELT approach•Part of Oracle Fusion Middleware•Customers can adopt either

Informatica or ODI, Informatica willcontinue to be supported


Customizing the Oracle Business Analytics Warehouse

•Although the OBAW comes with many star schemas and many ETL routines, you will probably wish to extend and customize it to meet your neds‣Include flex-field data‣Adding data from a custom source‣Adding new facts, dimensions, hierarchies

•Data can come from many sources‣Sources with adapters and existing load routines you can customize‣Sources with adapters but no load routines (source unsupported for subject area)‣Unsupported sources (using the Universal Adapter)


Customization Types

•OBAW customizations can be divided in to three categories‣Category 1 are where you add an additional column to an existing star schema‣Category 2 are where you add a new fact or dimension table‣Category 3 are where you add

additional rows to an existingfact or dimension, from anunsupported source


Customizing and Creating New OBAW ETL Routines

•Whichever type of customization you perform,you will be working with two mappings per target fact or dimension‣An SDE (Source-Dependent Extract) map

to extract data from the source system‣An SIL (Source-Independent Layer) map

to load data into the fact or dimension•Category 1 mappings involve customizing

existing SDE and SIL mappings•Category 2 customizations involve creating

new SDE and SIL mappings from scratch


A Typical Informatica ETL Mapping

•Data extracted from sources using “Mapplets”, encapsulated business logic•Data transformed using custom and pre-defined transformations•Standard keys, tags added to data as it passes through ETL process•Standard processes for adding surrogate keys, performing currency conversions etc•Mapping is then run and executed from the DAC Console and repository


Demonstration

The Oracle BI Applications ETL Process


Summary

•The Oracle Business Intelligence Applications are a packaged DW + Analytics solution for ERP and other data

•The base install of the Oracle BI Apps provides a pre-built set of data warehouse facts and dimensions, ETL routines, RPD metadata and control routines for a number of ERP modules

•You can extend and customize these mappings to bring in data not covered by the pre-built routines

•More details can be found on our website or in our Oracle BI Apps Developer Course
