Summary:  Data integration in an enterprise of data sources is one of the most common requirements of any database shop. Users need on demand integrated access to a variety of diverse data sources, such as traditional data assets like Excel spreadsheets and legacy data, to new and emerging technologies such as XML data stores. IBM® WebSphere® Information Integrator provides a single interface that allows end users and database administrators to virtually and transparently access a wide variety of these data sources. IBM Rational® Data Architect (Data Architect) works with WebSphere Information Integrator to give data architects and application developers the ability to discover, model, visualize, relate, and develop data assets across distributed and diverse data sources. In this tutorial, you follow a simple scenario to learn how Rational Data Architect can be used to provide a modeling and design tool to create a unified, virtual view across heterogeneous data sources.

Summary

What you learned

Rational Data Architect has enhanced and extended the capabilities of WebSphere Information Integrator to introduce a data modeling tool that can help you create and maintain databases and enterprise data models from heterogeneous data sources of any kind. With Data Architect, you can create new models or connect to existing data sources and automatically generate models from their schemas. Data Architect's intelligent mapping technology can discover how data is related between heterogeneous databases, letting you quickly design a new federated database.

In this tutorial you learned how to create a new logical data model and transform it to a physical data model that you can build on and eventually deploy to a database of your choice. You discovered two different kinds of data sources and browsed through their remote tables using embedded capabilities of WebSphere Information Integrator. You then reversed-engineered those remote databases to physical data models. You used the mapping and discovery capabilities to map the extracted physical models to the new data model and generate a view that defined those remote databases in terms of the new model. Finally, you deployed the generated view to a database and used it to access integrated data across the two databases in terms of the new model.
