A Reflective Model for Mobile Software Objects
Mobile software objects are autonomous computational entities that travel in large-scale and widely-distributed heterogeneous systems, and whose functionality can be attached to diverse computing environments. An object model that supports mobile objects should have special characteristics such as mutability of object’s structure and semantics to facilitate adjustment to different environments,...
متن کاملA System Prototype for Warehouse View Maintenance
A data warehouse collects and integrates data from multiple, autonomous, heterogeneous, sources. The warehouse e ectively maintains one or more materialized views over the source data. In this paper we describe the architecture of the Whips prototype system, which collects, transforms, and integrates data for the warehouse. We show how the required functionality can be divided among cooperating...
متن کاملAn Agent-based Communication Mechanism
The progress of information technology (IT) and the need for global distribution of geographic information is pushing the GIS community to deploy distributed Geographic Information Services (GIServices) on the Internet. Currently, on-line GIService research mainly focuses on technique-centered solutions without the consideration of the integration of heterogeneous GIService frameworks. This res...

متن کاملFramework for Object Migration in Federated
Existing federated database systems (FDBS) provide uniform access to multiple heterogeneous DBS, but do not enable objects to move across the DBS while retaining global identity. To fullll this requirement of industrial users, we provide a framework incorporating a exible object migration mechanism into FDBS. It ooers diierent capabilities for "what" and "how" to migrate: (1) diierent kinds of ...
