Database gateway allows clients using one communication protocol to connect with data servers that use a different protocol.
The Enterprise Connect™ Data Access (ECDA) product line consists of database gateway servers that allow clients using the Open Client and SAP Open Server protocol (such as Replication Server) to connect with non-SAP data servers, using either the data server’s native communication protocol or the standard, ODBC protocol.
Enterprise Connect Data Access products also allow the retrieval of metadata from non-ASE replicate data servers.
