> # Planning Your SequeLink® Server for ODBC Socket Configuration

> When your application connects to SequeLink Server for ODBC Socket, you can access any databases that are accessible through an ODBC 2.0, 3.0, or higher compliant driver. You only need a back-end ODBC driver, that is, the specific ODBC driver for the data store you want to access. Refer to the SequeLink Administrator's Guide for more information on configuring the SequeLink Server for ODBC Socket.

> To connect with ODBC drivers using SequeLink Server for ODBC Socket:

> 1. On the SequeLink Server, create an ODBC system data source for the back-end driver and check the connection. For information about defining the system data source using the ODBC Administrator, refer to your ODBC driver documentation.
> 2. Install the SequeLink Server for ODBC Socket. For more information, refer to the SequeLink Installation Guide.
> 3. On the SequeLink Server, create an ODBC Socket service.

> NOTE: Select the ODBC Socket service that meets the transliteration needs of the data store you want to access. For information on the different SequeLink services, refer to the SequeLink Administrator's Guide.

> 4. Create a SequeLink Server-side data source. Use the name of the data source that you created in Step 1 in the server-side data source connection string (the "DataSourceSOCODBCConnStr" attribute). This connection string consists of `DSN=`ODBC_system_DS, where ODBC_system_DS is the name of the ODBC system data source.

> NOTE: Installation of SequeLink Server for ODBC Socket automatically creates a server-side data source called Default.

> 5. On the SequeLink Client, create a SequeLink data source.
> - When connecting through the JDBC, .NET, or ODBC Client, no additional configuration tasks are needed.
> - If you are connecting to SequeLink Server for ODBC Socket through an ADO Client, you must perform additional configuration tasks. For detailed instructions, refer to the SequeLink Administrator's Guide.
