Oracle BI Applications: Overview

Oracle BI Applications is a complete, prebuilt Business Intelligence solution that both delivers Intuitive, role-based intelligence for everyone in an organization, from frontline employees to Senior management, and enables better decisions, actions, and business processes. Oracle BI Applications is a complete, end-to-end BI environment that includes the Oracle BI EE Platform and the prepackaged analytic applications. The platform includes a server and end-user tools such as dashboards, query and analysis, Enterprise reporting, and disconnected access to data, all supported by a unified, model-centric server architecture. On top of this platform, Oracle BI Applications consumes transactional operational data sources via packaged extract, transform, and load (ETL) mappings, and metadata, which load a data warehouse for analysis. Analyzing the data warehouse, Oracle BI Applications delivers rolebased analysis via prebuilt reports, dashboards, alerts, briefing books, and other channels provided by the platform. Oracle BI Applications Components Oracle BI Applications includes four main components:

1. Prebuilt extract, transform, and load (ETL) processes and tools to configure, customize, manage, monitor, and maintain the OBAW Prebuilt Informatica mappings and workflows



Informatica Integration Services for processing the prebuilt ETL mappings and workflows

Informatica tools for creating, customizing, extending, and testing the prebuilt Informatica mappings and workflows

Data Warehouse Administration Console (DAC) server and client with prebuilt metadata for configuring, running, and monitoring the ETL processes for source-specific containers

2. Prebuilt Oracle Business Analytics Warehouse data model with prebuilt star schemas and conforming dimensions

3. Prebuilt Oracle BI Server repository Logical business model mapped to physical data sources Key performance indicators and metrics definitions Presentation layer that exposes the business model to business users Administration Tool for building and customizing the repository Oracle BI Server for query processing

4. Prebuilt Oracle BI Presentation Catalog Prebuilt Interactive Dashboards and Oracle BI Answers reports Tools for modifying the prebuilt dashboards and reports Oracle BI

Oracle BI Applications Architecture The Oracle BI Applications architecture can be divided into four components:

1. Extract, transform, and load (ETL), including the Data Warehouse Administration Console (DAC), which is used to support extract from packaged and other source transactional data and load into the OBAW data warehouse.

2. Physical OBAW data warehouse data model for the Oracle Business Analytics Warehouse, which is designed to support multiple databases and provide an abstracted data model with conformed dimensions that support cross-domain analysis.

3. Server repository metadata, which provides physical to logical mappings, calculations, and metrics, as well as security

4. Presentation Catalog contents, including prebuilt role-based Interactive Dashboards, security, and analytics workflows and guided navigation



ETL Overview Three approaches to accessing or loading source data: • Batch ETL (Full or Incremental) • Micro ETL • Direct access to source data from Oracle BI server ETL Layered architecture for extract, universal staging, and load: • Provides isolation, modularity, and extensibility • Has the ability to support source system version changes quickly • Has the ability to extend with additional adaptors Architected for performance: • All mappings architected with incremental extractions • Highly optimized and concurrent loads • Bulk Loader enabled for all databases Data Warehouse Administration Console (DAC):



• Application administration, execution, and monitoring

Data Extraction and Load Process



The extraction process provides source-specific adaptors (Siebel/Oracle/SAP/PeopleSoft) as well as universal business adaptors, which are used for legacy or other data sources. Extract mappings encapsulate the complexity of the source and expose a simplified view of the business entities, loading data in a universal staging table format into staging tables in the OBAW. Data Extraction and Load Process After the data has been staged from various sources, the load process loads it into the warehouse, performing calculations and necessary aggregations before loading final destination tables in the OBAW. The load process manages slowly changing dimensions, which store historical versions of attribute data, generates and resolves warehouse keys, manages insert and update strategies, and performs currency conversions. Finally, the load process manages data consolidation, where by data from multiple sources, with different codes for similar respective entities, is standardized for common analysis in the OBAW.



Universal Business Adaptor

1. Universal Business Adaptors are used to extract and load data from nonpackaged sources.

2. The adaptors conform to the same extraction and load process, but provide generic sources, specifically flat file source definitions, to which data from legacy or other sources can be conformed for load during extract into the standardized OBAW staging tables.

3. Note: MQSeries is an IBM software family whose components are used to tie together other software applications so that they can work together. This type of application is often known as business integration software or middleware.

Data Warehouse Administration Console (DAC) The following are some of the elements to be deployed and managed in a data warehouse.

Data warehouse objects (tables/indices) ETL code Seed data Variety of configurations for ETL

The DAC is used to administer, install, maintain, and monitor ETL runs. It is also used by ETL administrators in production to monitor and restart jobs.



Physical Data Model: Overview

1. Is a modular enterprisewide data warehouse data model with conformed dimensions:

Sales, Service, Marketing, Distribution, Finance, Workforce, Operations, and Procurement

Data integrated from multiple data sources Code standardization

2. Stores transaction data in the most granular fashion 3. Tracks historical changes



4. Supports multiple currencies and languages 5. Is implemented and optimized for Oracle, SQL server, IBM UDB/390, and Teradata

Server Repository: Overview

The Oracle BI Application server repository contains metadata for three separate layers: Physical , logical, and presentation. Data from the physical layer is mapped to the logical layer, which includes the logical metrics, KPIs, and hierarchies to support analysis and drill paths.



The repository includes aggregate navigation, which describes the path used by report queries to access fact data, beginning, where possible, with appropriate aggregate fact tables for summary data, and then drilling further down to the transactional grain, where necessary, or for detailed analysis. The different types of fact tables in the OBAW are covered in the lesson titled “Oracle Business Analytics Warehouse Content.”

Metrics and Calculations The applications provide several complex metrics defined logically with an expression builder:

Share base (for example, percentage share of one product sales overall products sales) Indices (for example, this division’s performance as a ratio of all divisions) Cross-subject area metrics (across sales and workforce—for example, revenue per

employee) Variances (for example, Budget vs. Actual)

Time series metrics: Month to Date/Year to Date/Running balances/Moving Averages (for example,

Revenue Change percentage year to date) Period Ago Metrics (for example, revenue a year ago) Snapshot at any point of time (for example, number of open service requests)

Presentation Catalog: Overview

Oracle BI Applications delivers role-based Interactive Dashboards supporting organizational roles spanning from executives to line managers and individual contributors. Included in the dashboards, which contain tabular as well as graphical interactive elements and reports, are analytic workflows and guided analytics that help to drive critical business decisions and insight. Action Links, as described in the lesson titled “Oracle Business Intelligence Application Overview,” can drive the user from analytical reports and dashboards back to the transactional application in context to take action on the results of their analysis. Alerts and conditional highlighting provide ways to alert users to business-critical conditions, good and bad, and drive insight and action.



Oracle BI Enterprise Edition Platform Architecture



The diagram in the slide represents the logical relationship between the components of Oracle BI Enterprise Edition (EE). The physical architecture may vary, but a typical instance is described in this lesson. This logical architecture does not account for all utilities required to administer and extend the data warehouse.



Oracle BI EE is offered in two major architecture options: Oracle Business Intelligence Platform and Oracle Business Intelligence Applications. Oracle Business Intelligence Platform provides the following: • An infrastructure to model data so that users can understand it • A server to generate SQL and access, merge, and sort data from multiple sources • A simple, highly interactive, Web-based analysis tool, and the ability to construct dynamic reports and alerts Oracle BI Applications Architecture
