ODBC-Based Development
Open Database Connectivity (ODBC) is an MS API for accessing databases based on the X/OPEN CLI. The ODBC API alleviates applications from directly operating in databases, and enhances the database portability, extensibility, and maintainability.
Figure 1 shows the system structure of ODBC.
GaussDB(DWS) supports ODBC 3.5 in the following environments.

The operating systems listed above refer to the operating systems on which the ODBC program runs. They can be different from the operating systems where databases are deployed.
The ODBC Driver Manager running on UNIX or Linux can be unixODBC or iODBC. Select unixODBC-2.3.0 here as the component for connecting the database.
Windows has a native ODBC Driver Manager. You can locate Data Sources (ODBC) by choosing Control Panel > Administrative Tools.
The current database ODBC driver is based on an open source version and may be incompatible with GaussDB(DWS) data types, such as tinyint, smalldatetime, and nvarchar2.
