This job is considered about mobile technologies, and mobile devices data synchronization problem. Presented trading agent‘s mobile work places and server data synchronization solution, wich was developed using free software.

Information synchronization problems are analyzed in this thesis. Two aspects are being surveyed – clock synchronization, algorithms and their use, and data synchronization and maintaining the functionality of software at the times, when connection with database is broken. Existing products, their uses, cons and pros are overviewed. There are suggested models, how to solve these problems, which were implemented in “Distributed basketball competition registration and analysis software system”, and other theoretical solutions. Synchronization models are compared with other available solutions, the detail algorithms and methods are reviewed in this document.
