The SQL Gateway is an installed application that allows you to connect to ODBC data sources as if they were virtual MySQL or SQL Server databases.
The CData SQL Gateway enables remote access to ODBC data sources as virtual SQL Server or MySQL databases. The SQL Gateway application listens on a configured port for requests made in the MySQL or TDS (SQL Server) wire protocols and responds to those by reading from and writing to the ODBC data source. This allows you to connect to any ODBC DSN from remote machines, using any application that can work with either MySQL or SQL Server.
CData supports creating a linked server in SQL Server Management Studio with our ODBC drivers. This section describes the benefits of using a linked server, how to create a linked server, metadata discovery using a linked server, and executing queries from the linked server.
The CData ODBC Driver for AlloyDB integrates with MySQL clients through MySQL virtualization managed through the CData SQL Gateway application. The SQL Gateway enables you to create MySQL interfaces for ODBC data sources.
