In a real-time data warehouses, ETL is no longer executed periodically during the idle time of data warehouses, but continuously ongoing. Thus the triggering of ETL task, and In a real-time data warehouses, ETL is no longer executed periodically during the idle time of data warehouses, but continuously ongoing. Thus the triggering of ETL task, and the scheduling of updates and queries become the key...
The polymorphic, diversified, multi-sources and multi-use scientific data is quite different from the other data, there are many new challenges in building Scientific Data Management and Analysis System (SDMAS), especial one is that the multi-use data requires alternate classifications and mappings between them. Based on the oceanographic data, we present the solutions of multi-classifications problems...
The high level architecture (HLA) for distributed simulation was proposed by the Defense Modeling and Simulation Office of the Department of Defense (DOD) in order to support interoperability among simulations as well as reuse of simulation models. One aspect of reusability is to collect and analyze data generated in simulation exercises, including a record of events that occur during the execution,...
Today, most of the information query servers typically use the centralized approach where each servers are isolated from one another. In a large scale grid setup where there are many organizations, each with their own information servers, it is not feasible to deploy a centralized database to aggregate all the data. Using a peer-to-peer (P2P) approach allows us to connect each of the individual information...
