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.

Introduction to XML


XML files employ a format in which data is contained in a nested, hierarchical structure of tags which give context and meaning to the data contained between and within the tags. It has been described as similar to HTML because both in XML and in HTML the tags used can each have attributes, can surround data value elements (in HTML these are mostly text strings to be displayed), and can support deeper nesting of tag structures.

Where tags surround data or a deeper structure, they have opening tags balanced with closing tags, those nested inner tags always being closed before outer tags as in this snippet of HTML:

<b>This text will be displayed as bold <i>and this as bold italics</i></b>.

Where a tag has attributes, but doesn't surround any data or other elements, the opening and closing tags can be combined into one, with a closing "slash-bracket":

<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />

However, a big distinction...
