Design and implementation of enterprise systems in fine-grained concurrent computation

The computational power required to an enterprise system changes dynamically depending on services and the number of users. Massive concurrent computing is excellent in scalability, so that the paper proposes utilizing it for designing and implementing enterprise systems. The proposed accounting system is developed using Agile software development method to study the scalability of massive concurrent systems. When combining two subsystems in Agile, an attaching function is introduced. The system is designed using Model-View-Control software architecture and communicating sequential processes and then implemented with JCSP. Before implementation, the validity of the model is verified using verification tools. It reduces development cost and time. (C) 2012 Published by Elsevier Ltd.
