Daffodil Replicator is a data synchronization tool that provides a Java application capability to synchronize multiple data sources - some of which may be residing on a remote network. Daffodil's database synchronization tool allows its users to develop Java database for applications that can replicate and synchronize data between distributed Java-enabled databases. Replicator integrates impeccably with all Daffodil database products as well as with selected third-party databases that provide JDBC drivers.

Replicator Features- Data Synchronization between enterprise databases running on J2EE server platforms, workgroup databases running on J2EE/J2SE platforms and Java-enabled mobile devices running on J2SE/J2ME platforms
- Platform independent synchronization: 100% Java client and server components.
- Database-to-Database bidirectional data synchronization with client-side initiating the synchronization process.
- Publish and Subscribe model with a Publisher (Server) and Subscriber (Client) architecture.
- No need for Daffodil DB installation.
- Replicator working model
Conformation to Publication and Subscription- The Publication ( collection of one or more tables defined by developers) and Subscription (a subset of a particular publication on a Publisher) allows a Publisher to publish data to one or more Subscribers where Replication server enacts the role of a listener on a pre-defined communication port and the Subscriber makes periodic requests for data synchronization operations.
Publisher- Publishers are the basic building blocks of a Replicator's synchronization network . Each publisher forms part of a server-client network and is assigned a unique name. The name as well as the other concerned data of each publisher are stored in the publisher database i.e. all relevant information about the publishers, is stored in a database.
Subscriber- Subscriber subscribes to Publisher's publications.
- Replicator Publisher and Replicator Subscriber are responsible for managing the synchronization of data across the network. Both the Publisher and Subscriber are objects instantiated by user applications and perform the core functions associated with the synchronization of data. The Replication Server API gives method calls to Publisher and Subscriber, which enable Subscriber to perform synchronization operations.
