CLOUD DB SYNCHRONIZATION METHOD APPLIED .NET REMOTING TECHNOLOGY AND CLOUD-BASED POS SYSTEM

摘要

The present invention relates to a dot net remoting (.Net Remoting) technology and, more specifically to a method for synchronizing cloud DB by using the .Net Remoting technology for the access to classes existing between application domains of different processes or different hosts, and a cloud based point of scale system (POS system) by using the method for synchronizing cloud DB. The method for synchronizing cloud DB includes the steps of synchronizing the DB of a store sector server and a cloud server through the internet in usual; the sector server running the DB of the store individually and the cloud server not running the cloud DB individually when errors on the internet occur; and the sector server and the cloud server automatically connected and the changes made during the individual execution being synchronized with the cloud DB when the internet is recovered.
