Evaluating the Quality of Integrated Software Systems Based on Service-Oriented Architecture

Abstract

Most current systems operate independently of each other. When the organization needs a comprehensive system, it dispenses the existing systems to build a new one. Such strategy wastes resources and time. The integration of existing systems saves time, resources and it prevents risks in the new system. Moreover, using the quality model ensures that the system after integration is working correctly. The main objective of this research is to propose a model that could be used to evaluate the quality of integrated systems. The proposed model specifies the attributes that determine the quality of integrated systems. In order to measure these attributes a set of metrics were identified such as Existence of meta-information, Mean Time to Repair, and Mean Time between Failures. In order to validate the model two systems were selected and integrated using SOA technology. The results of the evaluation process showed high rate for the reusability, correctness, and reliability, normal rate for the usability, performance and modifiability.
