Software developers can build their systems by multiple invocations of these services. This research is devoted to investigating the management and data flow control over enterprise academic web applications where web services and developed academic web application are constructing infrastructure-networking scheme at the application level. Academic web services are invoked over http port and using REST based protocol;thus traditional access control method is not enough to control the follow of data using host and port information. The new cloud based access control rules proposed here are to be designed and implemented to work at this level. The new proposed access control architecture will be a web service gateway, and it published itself as a service (SaaS). We used three case studies to test our moodle and then we apply JSON parsers to perceive web service description file (WSDL file) and supply policies according to data are to be allowed or denied based on user roll through our parsing.展开更多

This online application allows to replace Excel based manual grades processing with fully automated one. Thus, the application helps to minimize the errors caused by the Excel manipulation. It also allows rapid centralization of all results at the exam service level. For the development, we adopted the agile method. This method is very efficient in allowing us to prioritize our real needs and the application is enriched as these needs arise. For the design, we used the UML Modeling language and for the implementation, we used a number of computer tools such as PHP, JavaScript, HTML, Jquery, AJAX, Bootstrap and CSS.展开更多

Testing these systems, due to their inherent complexities and special characteristics, is complex, time-consuming and challenging. In this paper a novel multi-agent framework for automated testing of web-based systems is presented. The main design goals have been to develop an effective and flexible framework that supports different types of tests and utilize different sources of information about the system under test to automate the test process. A prototype of the proposed framework has been implemented and is used to perform some experiments. The results are promising and prove the overall design of the framework.展开更多
