The centralization of a computer system makes the administration of the data, the equipment infrastructure and the software considerably easier. Creating and storing of backup copies, the management of application versions, the care about the equipment, which so far required a presence of qualified IT specialists in every company branch are transferred to one place and handed over to one team, which can manage these issues much more swiftly. All implementations of new applications or modules, which so far required numerous visits in individual branches, become much easier, as they are performed in one place and at one time.
