IBM Informix ODBC Driver with a driver manager

There is software architecture when a driver manager is included in the system.

The following figure shows the software architecture when a driver manager is included in the system. In such a system, the driver and driver manager act like a single unit that processes function calls.
Figure 1. IBM Informix ODBC Driver with a driver manager
This graphic illustrates the software architecture for Informix ODBC Driver when a driver manager is incorporated into the system. The graphic contains two groups of rectangles, one horizontally aligned, and one vertically aligned. The horizontal grouping of labeled rectangles is on the left side, is labeled “Client”, and contains three rectangles labeled, from left to right, "Application", "Driver Manager", and "IBM Informix ODBC Driver." There are dual-directional arrows that connect "Application" and "Driver Manager" as well as "Driver Manager" and "IBM Informix ODBC Driver." "Driver Manager" and "IBM Informix ODBC Driver" are grouped together to indicate that they act as a single unit in this situation. The vertical grouping of rectangles is labeled "Server" and contains two smaller groupings of rectangles, both labeled “IBM Informix data source." Each of the smaller groupings of rectangles has three rectangles labeled "DBMS (including database server)”, "database", and "Operating system and network software". The two "IBM Informix data source" groupings are joined by a dual-directional arrow that also connects to the "IBM Informix ODBC Driver" rectangle in the "Client" grouping of rectangles.
