View Generator (VG): a mobile agent based system for the creation and maintenance of Web views

The View Generator (VG) is a system that provides the necessary components for the definition, materialization, storage, maintenance and re-use of views over remote web-accessible databases. Through the system, clients identify web databases of interest, access their metadata and create personalized views that can be shared by other clients. Creating personalized views provides a more efficient way of data processing than directly issuing complex queries to the data sources especially in the case of light-weight and wireless clients that suffer from scarce local resources, limited bandwidth and high communication costs. VG’s multi-tier architecture implemented using mobile Java agents allows automatic code deployment as well as dynamic relocation of views.
