Once the drivers are loaded, the driver manager translates applications' function calls into the corresponding ODBC API calls, and it issues these calls to the drivers. It responds to all ODBC connection requests made by applications, and it loads the ODBC drivers that are associated with the requests. The driver manager is a library, which manages communications between applications and ODBC drivers. These calls enable the application to connect to the data store and query the data store via the ODBC driver. These API calls are implemented by ODBC drivers that are customized for use with the data store. ODBC-compliant applications are executables, which issue ODBC API calls. Most end users use ODBC-compliant applications to access their data stores. ODBC data access comprises the following, four components: Application Oracle Single-Tier drivers recognize these specialized parameters.MS SQL Server Single-Tier drivers recognize these specialized parameters.Configuring Mac Classic Data Source Names.The Multi-Tier Administrative Assistant.Setting Environment Variables on Darwin.ODBC Driver Architecture without Driver Manager.ODBC Driver Architecture with Driver Manager.
