A database gateway allows clients using one communication protocol to connect with data servers that use a different protocol.
The Sybase Enterprise Connect Data Access product line consists of database gateway servers that allow clients using the Sybase Open Client and Open Server protocol (such as Replication Server) to connect with non-Sybase data servers, using either the data server’s native communication protocol or the standard, ODBC protocol.
Sybase Enterprise Connect Data Access products also allow for the retrieval of metadata from non-ASE replicate data servers.
For more information about Enterprise Connect Data Access database gateways, see “ECDA”.
Sybase also provides the Mainframe Connect DB2 UDB Option for CICS product that allows “gatewayless” connections to IBM DB2 UDB data servers on IBM z/OS platforms. In some environments, a gatewayless connection to the DB2 data server may be more efficient than a gateway server connection.
Replication Server does not need an additional gateway to communicate with ASE and SQL Anywhere, which are both Sybase products.
