Requirements-Driven Software Reengineering
This event took place on Tuesday 25 April 2006 at 10:00

Dr Yijun Yu University of Toronto

As illustrated by the Horseshoe model, a software reengineering process improves a software system by reverse engineering it into high-level abstractions that can be used in the forward software engineering. Unlike traditional reengineering processes that recover abstractions at the level of architectural design, here I show that more abstract descriptions can be recovered at the requirements level, as goals of the stakeholders. The recovered requirements are then used as the basis to reengineer the system. Combining them with new stakeholder requirements for the system-to-be, a high-variability architectural design can be derived.

Future Internet is...


Future Internet
With over a billion users, today's Internet is arguably the most successful human artifact ever created. The Internet's physical infrastructure, software, and content now play an integral part of the lives of everyone on the planet, whether they interact with it directly or not. Now nearing its fifth decade, the Internet has shown remarkable resilience and flexibility in the face of ever increasing numbers of users, data volume, and changing usage patterns, but faces growing challenges in meetings the needs of our knowledge society. Globally, many major initiatives are underway to address the need for more scientific research, physical infrastructure investment, better education, and better utilisation of the Internet. Within Japan, USA and Europe major new initiatives have begun in the area.

To succeed the Future Internet will need to address a number of cross-cutting challenges including:

  • Scalability in the face of peer-to-peer traffic, decentralisation, and increased openness

  • Trust when government, medical, financial, personal data are increasingly trusted to the cloud, and middleware will increasingly use dynamic service selection

  • Interoperability of semantic data and metadata, and of services which will be dynamically orchestrated

  • Pervasive usability for users of mobile devices, different languages, cultures and physical abilities

  • Mobility for users who expect a seamless experience across spaces, devices, and velocities
