Data Synchronization in Distributed Information Systems

Amons O.A.

In the article proposes a data synchronization mechanism in distributed systems based on the types of work with tables and the integration of data versioning elements. Investigation focused on solving tasks support the relevance of the data on the individual nodes of a distributed system. Analyzed the distributed system features in which each individual node has a local copy of the data with which it works and periodically synchronize data with a central server. A general approach has been proposed to solving the problem of ensuring relevance and coherence state of the information for each user of the system by means of doing versioning control of data, recording the changed data and resolving conflicts that arise in the process of synchronization. The models used for the approach implementation have been considered.
