The thesis deals with methods of real-time data synchronization among multiple clients. The thesis focuses on methods in collaborative RIA systems running on the Internet This methods solve data transfer and conflict resolution caused by competitive clients work on one document. The introduction describes two methods: an established Operational transformation method and the new Differential synchronization method. The thesis describes the principles of both methods and their advantages and disadvantages. The aim of the work is implementing and comparison of Differential Synchronization method with Operational transformation method. These methods are compared in Node.js environment of JavaScript programming language and it is compared their performance in terms of response time and resource requirements. It's identified a problems associated with the method implementations in Node.js and it is described solutions of this problems. In the practical part thesis focus on the describing of performance data and behave of methods during measurement and refuted or confirmed the premises of methods definition assumptions. The Differential Synchronization method is extended by some parts based on the author often criticized issues of method.
