Reliability is crucial to the design and implementation of web service composition (WSC). In this paper, we propose a DTMC based approach for reliability prediction of WSC. First, we use SDG (Service Dependency Graph) to model the execution scenario of WSC. Then the SDG is aggregated, and its reliability is calculated using DTMC. At last, sensitivity analysis is conducted based on the execution scenarios...
Web applications support more and more our daily activities, it's important to improve their reliability and security. The content which users input to Web applications' server-side is named un-trusted content. Un-trusted content has a significant impact on the reliability and security of Web applications, so detecting the un-trusted variables in server-side program is important for improving the...
The data dependence analysis is a hard problem, particularly in the presence of data structures similar to the pointer. The inheritance and the polymorphism in object-oriented languages provide program design and software engineering with new methods. But, at the same time, they bring about more barriers to dependence analysis for object-oriented languages. This paper proposes an object-oriented data...
