SERVICE ORIENTED ARCHITECTURE ADOPTION IN E-EDUCATION SYSTEM

The introduction of a Service-Oriented Architecture (SOA) can affect performance in a negative way. This exacerbates the application of SOA to systems for bulk data processing. This paper describes specific aspects of Service-Oriented Architectures that impact performance particularly. It discusses several approaches to these issues that are currently established and motivates the need for a fr...

Service-oriented computing, which offers more flexible means for application development, is gaining popularity. Service-oriented grid applications are constructed by selecting and composing appropriate services. They are one kind of promising applications in grid environments. However, the dynamism and autonomy of environments make the issues of dynamically adapting a service-oriented grid app...

We present a systematic means of designing serviceoriented systems. Because services are developed independently, with no prior knowledge about each other, there is only a limited possibility that such services use similar message templates, initiate calls to any other service, or generate messages to support desired architecture configurations. As a result, construction of service-oriented sys...

As a matter of fact, SOA-based systems have a huge internal complexity due to plenty of services. On the one hand, this complexity enables and strongly supports the flexible alignment of the enterprise architecture with business processes. On the other hand, it requires a special management and control framework – provided by SOA Governance. For IT Governance, many accepted approaches exist. In...
