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.

Chapter 3. Using Variables

A very important element in all development environments is the ability to leave room for dynamic information. Eventually, you will want to use variables to construct, refresh, and store information as the processes unfold.

This chapter is relatively independent from the others, and can be consulted out of sequence. You will probably want to review some of its content after you have covered more of the following chapters. As variables can be used anywhere in ODI, some of the concepts mentioned here will actually be covered more in depth later. Introducing variables early will allow you to have a better feel for what they are and how and where they can be used. Other chapters will reference variables. Feel free to come back to this chapter for more details on the subject. In this chapter, we will cover the following points:

  • How to define variables, and how the different definitions will impact the usability of variables

  • How to use variables to process dynamic information...
