Sybase Enterprise Connect™ Data Access (ECDA) is an integrated set of software applications and connectivity tools that allows you to access data within a heterogeneous database environment. ECDA gives you the ability to access a variety of LAN-based, non-Sybase data sources, as well as mainframe data sources. It consists of components that provide transparent data access within an enterprise. You require a specific ECDA component for each actively supported non-ASE database that does not already provide an Open Server interface. This is required for replication to the non-ASE database.
ExpressConnect for Oracle, which is available with Replication Server Options 15.5 and later, provides direct communication between Replication Server and a replicate Oracle data server. ExpressConnect for Oracle eliminates the need for installing and setting up a separate gateway server, thereby improving performance and reducing the complexities of managing a replication system.
See the Replication Server Heterogeneous Replication Guide and the Replication Server Options documentation.
