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.

Defining Physical Schemas, Logical Schemas, and Contexts


In order to access or populate data, ODI needs to know where that data resides. The physical locations and connection criteria for servers and the Physical Schemas are defined in the Topology Navigator, under the Physical Architecture. The connection details of the servers and schemas will vary from environment to environment (development environment, testing environment, production environment, and any other environment you have) but the data on these servers will be organized the same way. To shelter developers from these implementation variations, developers will only have to know about one name for all environments, called the Logical Schema (think of it as an alias for all physical connections). A Context will be created for each environment, so that when needed, the Logical Schema can point to the appropriate physical connection. We will now see these elements in more detail.
