Do I need an ODBC Driver Manager to use the ODBC-ODBC Bridge?

The ODBC-ODBC client does not need a Driver Manager as you can link your application directly to it. The client contains much of the Driver Manager functionality, and this is how the ODBC-ODBC Bridge can support multiple versions of the ODBC API. When building PHP, Perl DBD:ODBC, Python mxODBC, and Rexx/SQL against the ODBC-ODBC Bridge you don't need a Driver Manager. If you write your own application, you can also built it against the ODBC-ODBC Bridge.

Some applications include a Driver Manager. For example, Applixware includes iODBC. The ODBC-ODBC Bridge will work just as well with a Driver Manager

If you have multiple ODBC drivers and you want to pick which one you use at run time, you need a Driver Manager. On Linux and UNIX platforms, Easysoft recommend the unixODBC Driver Manager. The Easysoft ODBC-ODBC Bridge distributions for these platforms contain the unixODBC Driver Manager.
