Integration, optimization and usability of enterprise applications

Many enterprises rely on a wide variety of collaborative applications in order to support their everyday activities and to share resources. The collaborative applications are typically designed from scratch if the existing applications do not meet the enterprise's evolving needs. This incurs significant costs, and inconvenience. In this paper we present a case study of six applications (Sage 200, Gold-Vision CRM system, E-Commerce System, Gold-Vision Connect System, Realex Transaction and Spindle Document Automation Tool) within an enterprise. These applications are working in isolation. Therefore, sharing of information and data among these applications is carried out manually which imposes additional burden on their users and causes performance degradation. In this paper, we address this problem by integration and optimization of these applications by applying Service-Oriented Architecture (SOA) approach. We also address the usability problems of these applications. We present comparative evaluation results that show significant improvement in ease and performance of user tasks using integrated applications.
