There are two options in ECDA:
ECDA Option for ODBC
ECDA Option for Oracle
Through DirectConnect servers, the ECDA Options provide basic connectivity to non-Sybase data sources. In particular, they provide data access, transaction management, and remote systems management through DirectConnect Manager.
DirectConnect servers provide connectivity between clients located throughout the enterprise and enterprise data servers. You can combine DirectConnect servers with ASE or Replication Server to can access, move, and replicate data in a heterogeneous environment.
DirectConnect servers are discussed in more detail in Chapter 2, “ECDA Option for ODBC” and Chapter 3, “ECDA Option for Oracle.”
