Besides the fact that FreeDAC is ready for multy threading environment, it offers "simple to use" features not requiring from a programmer to deal with threading.
FreeDAC allows to control timing aspects of data access operation execution. It includes Execute, Open and Fetch operations. A programmer can specify timeout (ResourceOptions. AsyncCmdTimeout) for data access operation execution and choose among 4 modes (AsyncCmdMode). In Cancel Dialog mode, a user will be notified about long running operation. The dialog form is shown below.
