A relational artificial intelligence system is invented and developed. It comprises a relational automatic knowledge acquisition system and a relational reasoning system. The relational automatic knowledge acquisition system is a relational learning system which discovers knowledges from spreadsheet-formed databases and generates relational knowledge bases using inductive learning technique. The relational reasoning system is a relational knowledge-based system which reasons about the generated relational knowledge bases automatically and predicts what will happen under future data readings. The feature of this invention is that every component in this system is relational. Not only the database to be read and the knowledge base to be generated, but also the inductive engine and the inference engine are relational. In the whole reading, operating, and generating processes, data are organized in the spreadsheet-form, and hence the system works with high efficiency and speed.
