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.

Implementing Slowly Changing Dimensions (SCD) using ODI

If the reader is familiar with the fundamentals of data warehouse design, there should already be an understanding of three basic forms of dimension management:

Type-I: No historical data (new record data replaces the old data)
Type-II: Complete historical data (with start and end date bracketing)
Type-III: Limited historical data (only the most recent data is kept)

Note

There are other SCD methods (that is history tables, hybrids, and so on) not mentioned, but due to the infrequency of their use or lack of support by ODI, they have been omitted from this discussion. It is not within the scope of this book to discuss the advantages, disadvantages, and reasons for using any of these SCD formats, rather, we will simply describe which of these types have been addressed by ODI.
