DPD-Tool of Healthcare Applications– Supports functionalities of the DOGF via application interfaces for

conveniently developing distributed healthcare applications.– Providing the group management and the distributed services by

calling the simple Application Program Interfaces(APIs).

• Client/server programming developers can conveniently implement distributed applications.

• Independent of any kind of application programming language and distributed middleware.
