  7. Today’s Agenda • The Challenge • The Architecture • Future Models • A Methodology • Conclusions

  8. What is a Reference Architecture? A Reference Architecture “describes a high level system design and guidelines for engineering …” modern, component-based enterprise applications.

  9. We understand… One size does not fit all! What is theOpenEdge Reference Architecture? • Aguideto best practices in application development • A map for Progress products and their applicability • A method for delivering competitive advantage

  10. Anticipate trends in technology Accommodate evolving business requirements Manage complexity Optimize planning and resources Reuse valuable intellectual property A Guide to Best Practices Good Software Architectures - Stand the Test of Time! • Provide a Solid, Modern Foundation for Competitive Business Applications

Distributed Client Architecture Evolution AppServer Business Process Business Process Business Process Technology Transformation Has driven architecture transformation Application development and application architectures have had an interesting and sometimes painful evolution Process-OrientedApplications HostCentric ClientServer • Service-Oriented Architecture (SOA) is the next-generation interoperation methodology • Technologies such as Web Services are a means to that end

  20. Business Logic … they do not exist as an island. Interoperability and integrationis an inherent requirement. Integration User Interface Guiding Principles of OpenEdge … applications are a collection of software components that reflect changing business processes. … and are not bound by any one user interface technology, methodology, or platform.

  30. Extract from “Architectures and Patterns for Software Infrastructure” Gartner Research note, 28 January 2003 “In the future, applications will increasingly be implemented by combining new developments and pre-existing systems, and by chaining business components - often referred to as "services " - that run on multiple systems. Business components will be technologically diverse and may even belong to different technology generations." Massimo Pezzini
