When did the expert database system flourish?

The origin of expert database system can be traced back to the United States in the early 1970s. In order to better deal with various domestic and international problems, the US government has set up an expert advisory group, where experts provide opinions and suggestions. The form of these expert consultation groups has gradually evolved into an expert database system, that is, the government or enterprises centrally manage expert information in professional fields so as to obtain professional opinions and suggestions at any time when needed.
