Oracle Fusion Middleware combines all the key SOA standards together into a common service infrastructure. Such a service infrastructure is in turn shared throughout the entire middleware platform. This guarantees a common, interoperable basis for the deployment of the next generation of enterprise applications.
Developers can thus configure services that have been deployed upon the service infrastructure in order to leverage such standards through the use of a composite service descriptor, as has been described the Service Component Architecture standard.
This model presents an elegant mechanism for the combination of all the standards into a simple description of services as well as their relationships. As standards are considered to be the starting point for all interoperability, Web services that are constructed with Oracle Fusion Middleware tend to conform to two profiles delineated by the main industry consortium on interoperability.
One is the WS Interoperability Basic Profile 1.1, while the other is the Basic Security Profile 1.0. What is more, Oracle makes extensive use of testing frameworks that are focused solely on interoperability with major vendor platforms as well as open source web services stacks.
Oracle also participates in interoperability events that are open to the public where vendors can validate interoperability among platforms. This gives application developers a foundation upon which they may then build interoperable services that can be readily coordinated in the formation of composite applications.
Oracle Fusion Middleware is renowned for providing comprehensive infrastructures and tooling for the deployment and development of service-oriented applications that are based on J2EE applications, as well as ESB flows and BPEL processes.
Through the usage of unified Service Oriented Architecture tools that are provided in Oracle Jdeveloper, it is vital to bring services together in to a new generation of business processes and composite services. Once they are built, the services can then be deployed to an SCA based service infrastructure, which is a run time environment that renders a common bus for both network connectivity and the delivery of messages. The service infrastructure is then shared across the Fusion Middleware Platform, allowing single infrastructure to provide such services to the full product suite.
With Visual Studio .NET, developers are now able to support dotnet objects directly through common language run time services that effectively remove coding responsibilities from the developers. Without the presence of a Service Oriented Architecture, such as the .NET framework provides, there is a lot more coding that has to be done by each developer who is working on the construction of a given system – there is even more coding at stake for the building of reusable common code for numerous systems.
This is why the utilization of a consistent, common framework for the deliverance of CLR based applications can drive a lot of developers to design services that are more reusable than the services found in the COM format. The only question that remains is to whether dotnet developers will begin to proactively design new applications in the form of flexible service oriented systems or whether service orientation in dotnet format will be merely an afterthought.
