Abstract

In this paper we introduce and discuss a model of distributed data processing. For this purpose, a typical application system is analyzed and divided into sub-applications. To fulfill the task of the global application, the sub-applications have to communicate in an appropriate manner by exchanging data resp. information. In our model the communication between sub-applications is split up into two steps: the offering of information by sending sub-applications, and its acceptance by receiving sub-applications. For both communication steps synchronous and asynchronous processing modes are defined. Supporting those different communication modes the cooperation between sub-applications can be defined very closely to the specific demands of the application system. This optimizes distributed data processing. At last we demonstrate the prototype implementation of a distributed data management system, which is based on the flexible communication mechanism described in the paper.
