Overview

Derby/G is a research prototype implementing the GORDA Architecture and Programming Interface (GAPI) on Apache Derby. This implementation is tightly coupled with the database server and aims at fully demonstrating the GORDA Interface.

Note that an implementation of the GAPI does not provide a complete replication solution. A replication protocol, such as the ESCADA Replication Server, is required.
