ECDA is an integrated set of software applications and connectivity tools that you can use 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. ECDA components allow Replication Server to replicate to non-Sybase DBMSs, such as IBM DB2 UDB, Microsoft SQL Server, and Oracle.
