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.

Physical federation products


Physical federation, as the name implies, involves physically moving data from its target data source into an Oracle Online Transaction Processing (OLTP) system, Data Warehouse (DW) or Operational Data Store (ODS). The data movement may take place using bulk file transport, data streaming through ODBC or JDBC, a messaging system, reading of database log files or any information integration mechanism.

Traditionally, physical federation has been associated with enterprise data warehousing. Master Data Management and data hubs have moved physical federation from being a read-only database (such as a data warehouse or data mart) to a component of a company's OLTP infrastructure. This complicates the situation as solutions like Change Data Capture (CDC), bi-directional replication, and data write back to the source may be required.

Since we are pulling data in many cases from legacy environments, non-Oracle databases, or consolidating information that may have duplicate...
