ODBC SDK for Mac

From August Software:

ODBC SDK is a free download that enables Carbon and Classic Mac C/C++, PERL and PHP developers to build royalty-free apps that can access virtually all SQL database systems by way of their standard Windows ODBC drivers installed on a central Windows PC equipped with our ODBC ROUTER. In this way, technical support is reduced as end-users are not required to install and maintain third-party Mac ODBC control panels and drivers on each client in their network (all configuration takes place on the central Windows PC). ODBCSDK is free; end-user licensing for ODBC ROUTER starts at $99 with discounts available for education and health services.
