C5: Introduction to DataXtend Semantic Integrator  (Presentation)
Speaker: Dean Elliot, Business Development Manager, Progress Software

Enterprises today need to increase the agility of their IT infrastructure to be able to react more quickly to changing business goals. Many are rapidly adopting an SOA to address this. SOA on its own, however, does not address the issue of how data is represented differently across the many services that must interoperate. Many organizations simply implement point-to-point mappings between their services using Java or XSLT, but these hand-coded adapters reintroduce the brittleness at the data level that SOA was intended to eliminate. Implementing a common data model to mediate between these service endpoints is the solution to this data interoperability challenge.

In this session you'll learn how Progress DataXtend Semantic Integrator enables you to create, maintain and govern common model-based data services in your SOA implementations in order to bring SOA's promise of agility to data interoperability. In addition, you'll discover how, with DataXtend, data quality rules can be implemented on the common model to govern the quality of the information flowing through your SOA.
