Oracle Data Integrator 11g Cookbook

Oracle Data Integrator 11g Cookbook

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 batches, to SOA-enabled data services, to trickle operations, ODI is a cutting-edge platform that offers heterogeneous connectivity, enterprise-level deployment, and strong administrative, diagnostic, and management capabilities."Oracle Data Integrator 11g Cookbook" will take you on a journey past your first steps with ODI to a new level of proficiency, lifting the cover on many of the internals of the product to help you better leverage the most advanced features.The first part of this book will focus on the administrative tasks required for a successful deployment, moving on to showing you how to best leverage Knowledge Modules with explanations of their internals and focus on specific examples. Next we will look into some advanced coding techniques for interfaces, packages, models, and a focus on XML. Finally the book will lift the cover on web services as well as the ODI SDK, along with additional advanced techniques that may be unknown to many users.Throughout "Oracle Data Integrator 11g Cookbook", the authors convey real-world advice and best practices learned from their extensive hands-on experience.

Using Changed Data Capture (CDC) - simple

As mentioned during the introduction of this chapter, one of the more commonly used ETL/ELT methodologies is CDC. This generic term refers to the means by which a data migration design can identify source data, which has been altered in some way (that is, inserted, updated, or deleted). By focusing only on changed data, a migration strategy can avoid having to move an entire set of data, a process that is usually done only during an initial data load.

When determining which ODI KMs and CDC methods to use, a developer/architect should consider several of the following points:

The availability of pre-existing timestamp attributes on source systems tables
The database privileges required to create table triggers on the source system
The availability of database log files and corresponding internal CDC delivery mechanisms (that is, Oracle Logminer, Oracle Streams, and so on)
The availability of Oracle Golden Gate for specific technologies
