For me, I am a knowledge management system, what kind of system is also confused in my mind. Knowledge, there is an objective knowledge and subjective knowledge, and there is a potential knowledge and dominant knowledge. The so-called knowledge management system should be more focusing on the management of potential knowledge. If management is the dominant knowledge that has been recorded in the literature, it is easy to confuse the traditional information management system or a simple document management system. The knowledge management system will eventually emphasize the management of people. The simple relying software system is difficult to achieve knowledge management, and the requirements for software developers are too high.
