Abstract

The increasing demand for improving reliability existing e-education system, there are many efforts to integrate and automate design/analysis processes base on various distributed educational resources. A number of research efforts have been proposed SOA (Service Oriented Architecture)-based e-education framework for flexible integration and automation of the educational processes on the Web services environment. However, guaranteeing reliability in the educational process is one of the new problems that must be solved in the e-education framework. This paper presents two approaches to handle various exceptions that happen in the middle of the execution of the process. One is to introduce recovery activities into the educational process modeling to handle exceptions caused by failures of the educational resources; the other is to use log-based recovery techniques to recover from the system exceptions such as network failures or system crashes.
