Oracle Information Integration, Migration, and Consolidation

Overview of this book

The book covers data migration, data consolidation, and data integration, the three scenarios that are typically part of the information integration life cycle. Organizations typically find themselves migrating data to Oracle and either later, or at the same time, consolidating multiple database instances into a single global instance for a department, or even an entire company. The business savings and technical benefits of data consolidation cannot be overlooked, and this book will help you to use Oracle's technology to achieve these goals. This highly practical and business-applicable book will teach you to be successful with the latest Oracle data and application integration, migration, information life-cycle management, and consolidation products and technologies.In this book, you will gain hands-on advice about data consolidation, integration, and migration using tools and best practices. Along the way you will leverage products like Oracle Data Integrator, Oracle GoldenGate, and SQL Developer, as well as Data Hubs and 11gR2 Database. The book covers everything from the early background of information integration and the impact of SOA, to products like Oracle GoldenGate and Oracle Data Integrator. By the end you'll have a clear idea of where information and application integration is headed and how to plan your own projects.

Summary


In this chapter, we discussed the various options for enabling data integration, whether it be flat files, changed data capture, adapters, and so on. We took a closer look at the architecture, components of key Oracle technologies such as Oracle GoldenGate, Oracle Data Integrator, and Oracle Database Gateways that provide unique capabilities to support most data integration needs. Oracle GoldenGate is well suited for transaction replication to achieve high availability, load balancing between databases, maintenance of reporting databases in near real-time, and so on. Oracle Data Integrator provides powerful transformation capabilities for enterprise data warehousing in a declarative manner. Oracle Database Gateways on the other hand enables data federation in a unique way at the database tier, that is at SQL, and PL/SQL level, isolating developers from the complexities of the SQL Semantics, configuration, and so on in a heterogeneous environment.

Finally, the snapshot case study is...
