Abstract: The algorithms of "change detection for database content" and "change detecti on for file" were put forward for detecting the change of client con tent data based on the actuality of multilingual contents in the enterprises. An effectively centralized multilingual content management system was designe d and implemented by using the XML, CORBA(common object request broker architecture) and workflow technologies. Based on th e features of the multilingual contents, the system framework, workflow processe s, content change detection algorithms and system implementation were designed in detail. The feasibility of the algorithms and system design was verified by impl ementing the system.
