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 ODI Interfaces


Having had a look at data flows and the roles that KMs play within them, let's now dig a bit deeper into the make-up of the primary data flow component—an interface.

The interface component in ODI defines the following data flow properties:

  • The destination datastore for the data (the target). This will be chosen from an ODI model.

  • The datastores that supply the input data (the sources). These too will be chosen from ODI models.

  • The transformations that are applied to the data during the transition from sources to target (the mappings). These are expressed in SQL.

  • The physical transfer mechanisms that are used between sources and target (the flow). We have already seen that this role is performed by the Knowledge Modules.

The first two of these properties specify what we want to achieve in the interface. The flow specifies how it will be achieved.
