With the increased size and complexity of software products, software applications are often no longer created by an individual or even a single organization. Instead, applications now commonly comprise components produced by different developers using diverse practices. In order to minimize the complexity of this process, it is beneficial for those working in the field to standardize software development. Large software applications following traditional approaches are difficult to design and test, slow to develop, require continuous maintenance and updates, and are often unreliable. By constructing software products using emerging techniques, software engineers are seeking solutions to these problems and attempting to reduce the period of software development, while increasing productivity, security and reliability. The primary objective of the 12th IASTED International Conference on Software Engineering and Applications (SEA 2008) is to provide a forum for substantive discussion on the emerging technologies and methodologies being developed to overcome the challenges that exist in all areas of software engineering. This conference will also showcase developments in industry, successful applications, and case studies. All papers submitted to this conference will be double-blind peer reviewed by at least two members of the International Program Committee and related technical committees. Acceptance will be based primarily on originality, significance, technical soundness, presentation, and references. The conference chair makes the final decision on the acceptance or rejection of the paper. SEA 2009 will be held in conjunction with the IASTED International Conferences on: · Telehealth and Assistive Technology (TAT 2009) · Robotics and Applications (RA 2009) · Intelligent Systems and Control (ISC 2009) · Parallel and Distributed Computing and Systems (PDCS 2009)
