When the bill needs to be paid, the total is tallied by a cash register, and the waiter brings the bill to you. The cash register is a resource manager. It manages how the burgers, fries, and shakes you ordered are charged. The waiter is a resource dispenser. Resource managers are responsible for the state changes you have made to the resource, changes like storing a name or changing a person s address.
Resources can be databases, mail systems, etc.
The resource dispenser provides the handle to the resource manager. One example is the ODBC resource dispenser within the MTS system. In this article we re focusing on MTS.EXE, the DTC, and the COM component.
