Scalable Information Systems

This book constitutes the proceedings of the 4th International ICST Conference, INFOSCALE 2009, held in Hong Kong in June 2009.

Scalability has become a mainstream research area in computer science and information systems in view of the incessant growth of data and knowledge.

More than 60 manuscripts were submitted, and the program committee selected 22 papers for presentation on the conference and reproduction in this book. The papers focus on a wide range of scalability issues and new approaches to tackle problems arising from the ever growing size and complexity of information.
