Specifying a Connection Using dbExpress
Go Up to Connecting to the Application Server
When using DataSnap to communicate with the application server, client applications include a TSQLConnection component from the dbExpress category in the Tool Palette, for connecting to the application server. The Driver property of the TSQLConnection must be set to Datasnap.
The communication protocol for the drivers can be either TCP/IP (default) or HTTP. Although these offer the same functionality on the client side, different components are used on the server side.
