Getting Started with Oracle Data Integrator 11g: A Hands-On Tutorial

Overview of this book

Oracle Data Integrator (ODI) is Oracle's strategic data integration platform for high-speed data transformation and movement between different systems. From high-volume, SOA-enabled data services, to trickle operations ñ ODI is a cutting-edge platform that offers heterogeneous connectivity, enterprise-level deployment, and strong administrative, diagnostic, and management capabilities. "Getting Started with Oracle Data Integrator 11g: A Hands-On Tutorial" provides you with everything you to get up and running with Oracle Data Integrator, and more! Following an example scenario, the book covers essential information about the ODI architecture and using ODI across different databases (Oracle, Microsoft SQL Server and MySQL), and file types such as XML, before covering Orchestrating Data Integration Workflows, Error Management, Operational Management and Monitoring, and beyond. "Getting Started with Oracle Data Integrator 11g: A Hands-On Tutorial" begins by describing the Oracle Data Integrator architecture and teaching you to install the product following best practices. You'll then be introduced to some of the key concepts of ODI such as the Knowledge Modules. Later topics include moving and transforming data from sources to targets including the Oracle Database, Microsoft SQL Server, MySQL, Flat files, and XML files, each with illustrated hands-on examples for the different technologies. Your learning experience will be made all the more rich with chapters introducing, explaining and leveraging additional ODI functionality such as variables, reusable procedures, temporary indexes and more. Finally ODI's workflow and task orchestration capabilities are explained before introducing you to Error Management with ODI's built-in 'error hospital' and 'error recycling' capabilities for non-compliant data, not to mention tackling ODI Studio, ODI Console and Enterprise Manager Fusion Middleware Control.

Examining the anatomy of the interface flow


Once we've created all our definitions and references for the data that we want ODI to transform and transport, we can focus on what precisely it is that we want to take place in terms of data mappings and transformations, that is we can look into creating ODI Interfaces. We have already seen that ODI uses an E-LT approach and architecture, but what does that mean in detail? What actions are performed, where, and at what time during the overall flow, and what components will perform those actions?

In this section we will walk through three very simple yet common ODI data flows to examine and explain these aspects of ODI's operational behavior.

ODI Interfaces are the objects used to transform and transport data from one or more sources to a target, so each of these flow examples will be implemented in a separate interface.

Example 1: Database and file to database

This example forms the foundation of many ETL jobs. It's a simple case of loading data...
