Remarks

It provides functions to start-up and to execute the server engine. This server engine can handle multiple master connections and is implemented as a single threaded TCP server. Upon receipt of a valid master query the server engine calls Data Provider methods to exchange data with the user application.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
