Synchronization Barrier in Database Migration processes

Abstract

The systems helping us nowadays in some sectors, including health service, transportation, medicine, and many others, have one common thing: data. The data in the mentioned sectors help with the support of decision making, to manage systems, and to prevent dangerous situations. To the increasing amount of the data, a growing demand was related. In the current modern era, the data has become a commodity, and the data are traded like goods in many cases The systems, working with the massive amount of the data, do not only with values already in the system but also with the system's data in real-time. So, they influence many evaluation systems, respectively, they modify various statistics. The real data play a crucial part during transformation processes and the mutual affecting of the data. This article will create a synchronization barrier that will be used to influence the data during the data transformation from a relational database to a nonrelational database. The purpose of this barrier is to reduce the time needed for a data change from source database to target database and, by this, to reduce the number of operations that would be required to do after finishing the process just with incoming values.
