It might be silly question and i know for such systems they usually use Ontology authoring tools or Rule-based languages like CLIPS, but is it possible to create a Knowledge base by relational databases?
For example, let's say i want to create a recommendation system for diabetes patients.The application gets their blood glucose level and response a recommendation based on their health situation. (I guess this one could be easily implemented by a mapping table )
But what if other factors like Age, Male/Female,calorie intake etc add to the problem.
Is it still possible to design a knowledge base in which has the relation of these factors and a recommendation table?
