In this paper, we present a web service model to support snapshots replication in multiple database engines. This model is open and is composed by a set of web services, agents and a manage console that allows to perform administrative tasks independently from the application and the database engines. This model uses a replication master catalog (CMR) to store the replication data. We show the architecture used and the behavior of our replication model to provide a better understanding about the data replication, as well as, discussion of several papers related to the replication services independent from the database engines.
