The replication services available acquire high maturity and performance levels. However, they do not work with heterogeneous data bases. This dissertation first describes a software architecture that focus on how to provide replication services for heterogeneous bases. To obtain high scalability and to maintain simplicity, the architecture follows a multi- agent structure and adopts a domain-driven design approach. Then, the dissertation describes a reference implementation and discusses the technical decisions adopted, focusing on version control problems, consistency verification and specific businessoriented rules. The dissertation also describes utilities that facilitate the configuration and maintenance of the replication system.
