| Abstract: | This paper describes a strategy for actively replicating and updating content for electronic commerce. Active replication and updating of content is achieved by intelligent agents (IA) using time-invariant fragmentation approach to partitioning and replicating data in a distributed computing environment. Taking into account the time-sensitivity property of data, IAs derive time-invariant fragments for their respective nodes from the query history. A time-invariant fragment (TIF) is that portion of the database whose values do not change during a specified time interval. The algorithm that IAs use in creating TIFs for each node, for a given time interval, is presented. |
