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.

Preface

Oracle Database Gateways


Introduced in Oracle 9i, the Heterogeneous Services component of the Oracle database and the database gateways enables synchronous data integration between Oracle and non-Oracle databases in a transparent manner. The main advantage of this Oracle solution is that the database developers do not need to customize the applications based on the databases they are trying to access from an Oracle database-based application, in terms of using different APIs for different databases. Oracle enables the use of the same SQL dialect for all non-Oracle databases as Oracle. These gateways are optimized for the databases that they connect to and provide an end-to-end solution for integration with non-Oracle systems.

There are many benefits of an Oracle heterogeneous connectivity solution, including:

  • Consistent set of APIs (Oracle) for access to non-Oracle systems

  • Access to objects from non-Oracle systems in SQL Statements, views, triggers, stored procedures, and so on, without...
