METHOD AND PROGRAM FOR PROVIDING DATA COHERENCE IN NETWORKS

摘要

The present invention relates to a method and to a program for providing coherence between instances of data objects residing on distributed nodes of a non memory-coupled network. In order to create a method and a program for providing coherence in keeping with the characteristics described above, which allow coherence between basically arbitrary data objects or instances of data objects, in the process are largely freely scalable and also require no central memory or server for the data objects, it is proposed according to the invention that for each instance of a data object to be processed by a node platform-independent unique metadata is generated, and with the help of said metadata and a coherence protocol, which operates based on said metadata, the metadata and consequently the data objects are kept coherent.
