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 lightweight 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.
