DB2 Single-Tier
The Single-Tier ODBC Drivers for IBM DB/2 are a single component
installed on a data-consuming machine - depending on the architecture in
which the driver is deployed, either a client such as a desktop, a
workstation or an application-server machine. No components need be
installed on the database server.
The OpenLink Single-Tier Drivers for DB2 are a Type A class driver
developed using the DB2CLI call level interface and assumes the prior
installation of DB2Connect depending on your DB2 Server release.
