A server with server class aseodbc is:
Adaptive Server Enterprise
SQL Anywhere (version 10 and later)
Sybase IQ requires the local installation of the Adaptive Server Enterprise ODBC driver and Open Client connectivity libraries to connect to a remote Adaptive Server with class aseodbc. However, the performance is better than with the asejdbc class.
See”Server class aseodbc” in SQL Anywhere Server - SQL Usage.
