Abstract
Synchronizace dat umožňuje existence stejných dat na různých serverech. Tím je zajištěna redundance a rychlejšího zpracování. Tyto servery musí mít konzistentní a neustále dostupné údaje. Konzistenci a dostupnost dat lze zajistit synchronizací dat a replikací dat. Replikace dat zahrnuje vytvoření více než jedné redundantní kopie databáze ke zlepšení dostupnosti dat a také k tomu, aby byl systém odolný vůči chybám. Cílem této práce je představit studii, která by fungovala jako nástroj pro synchronizaci databází, s ohledem na konflikty, který tato duplikace informací může zapříčinit. Je použit algoritmus který zajišťuje synchronizaci pomocí nástroje na straně klienta. Tato studie je založena na experimentech na reálných datech, které ukazují, jak mohou synchronizační techniky řešit nesrovnalosti dat a zaručita jejich integritu.
Data synchronization ensure that a data set exists in different directory servers to ensure redundancy as well as faster processing. Such servers need to have data that is consistent and available at all times. Data consistency and availability can be assured by data synchronization and data replication. Data replication involves creation of more than one redundant database copies to improve on data accessibility as well as make the system fault tolerant. This thesis is intended to present a study a working tool for database synchronization without forgetting to look at conflict introduced by this duplication of information and their resolution. An algorithm that works to ensure synchronization using a client-side tool is used to present a working model. This study is based on experiments on real data to show how the synchronization techniques can solve the data inconsistencies and guarantee the integrity of the data
