Evaluating Web Services Functionality and Performance

Traditional distributed database transaction applications within large organizations often involve a large number of resources. In this case, people and DDBMSs distributed over a wide geographic area, may introduce conflict between heterogeneous systems. Web services (WS) provide solution for this problem since WS have an independent platform, independent language, and independent object model. This work presents WS application to access heterogeneous and distributed database via horizontal data fragments that is designed to be reliable, flexible and scalable. It describes the setup of SOAP server and applications based on the SOAP for end user client. In addition, it allows the publishing of WS descriptions to submit user requests (goal) to retrieve the required information. Here we evaluate the functional, behavior and performance of WS among possible different alternatives with real-time and execution parameters. Implementation details and case study experiments are presented along with the corresponding results.
