What is IBM Informix ODBC Driver?
Open Database Connectivity (ODBC) is a specification for
a database application programming interface (API).
IBM Informix ODBC Driver with the DMR IBM Informix ODBC Driver includes a Driver Manager Replacement (DMR) library. The
DMR replaces the driver manager on platforms where no driver manager

to make a connection to a data source, send SQL statements to a data
source, process result data dynamically, and terminate a connection.

the additional functions.
