Enhancing Contextual Data Storage in the Clouds

This book presents an investigation about organizational context cache utilizing various caching strategies and proposes a novel caching mechanism in cloud environment based context provisioning system. Contextual information about an entity has been biggest temporal aspects i.e. entity information, situation remains valid for a period of time. To bring the locality of reference into consideration, this temporal property can be exploited in caching strategy. Contextual information changes according to valid sessions. Application and database deployed in the cloud server and we can access data by using mobile devices. That's why this implementation is called Software as a Service (SaaS). The result shows relative benefits of three caching strategies.
