A Survey of
Information Replication Issues and the Use of Coordinated Replication in
Managing Content Development




Abstract


Replication is used to bring information from the information producer to the information consumer. Multiple types of replication may be deployed so that the user’s access to the information may be more timely and effortless. On the Internet, replication may be demand-triggered, that is, happening after the user issued a request to access the information. In this case, the information is copied to a “cache” geographically adjacent to the user before it is presented to the user. Replication may also be supply-triggered, when information is replicated to multiple servers in order to satisfy potentially heavy user demand. We will provide a review of the various replication scenarios and the issues involved.

We will also discuss a third type of replication – coordinated replication – and its use in the management of web content development. In this scenario, replication happens only after both the information producer and consumer have consented. A Java-based program for coordinated replication has been developed, and we show how it is used to automate the coordination and integration process between the various developer teams and between the developer teams and the quality assurance teams.
