All of our rules of inference are valid In other words they will never take you from true premises to a false conclusion?
Yes, rules of inference are valid inferences that guarantee truth-preservation. This means that if the premises of an argument are true, then the conclusion drawn using valid rules of inference will also be true. Rules of inference are based on sound logic and deductive reasoning to ensure that the conclusion accurately follows from the given premises.
When dbms becomes rdbms?
