Enterprise Connect™ Data Access (ECDA) 15.0.1 is built on Open Client™ 15.0 and Open Server™ 15.0 ESD #25. ECDA provides access to distributed data. See the Enterprise Connect Data Access Overview Guide.
There are two options for ECDA:
ECDA Option for ODBC (includes ECDA Option for DB2 UDB and the ECDA Option for Microsoft SQL Server)
ECDA Option for Oracle
WARNING! Sybase does not supply back-end drivers with ECDA to provide connectivity to non-Sybase target databases. You must obtain a separate license from Microsoft, Data Direct, or other vendors, for the ODBC driver that is needed on the particular platform where ECDA is running.
There is a list of back-end drivers that Sybase supports on the Certification Web site.
