Armstrong's Inference Rules
Logical inference.
Armstrong rules are complete or sound in dbms by clarifying the types of situations which need to be achieved and done.
Statistical inference occurs when
Define statistical inference and give an example
What is the use of statistical inference in technology?
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.

Inference involves drawing conclusions based on evidence and reasoning, while deduction involves reaching a specific conclusion based on a set of premises or rules.
theorem
The inference rules in DBMS describes the New functional Dependency derived from two existed entity which are functionally dependent. For example: let two entities X and Y, if X belongs to Y and Y belongs Z then X must belongs to Z. This rule called transitive rule. Thanx Subhash(820740207) PTU 4th Semester Patel nagar Delhi
Inference is the act or process of deriving logical conclusions from premises known or assumed to be true.The conclusion drawn is also called an idiomatic. The laws of valid inference are studied in the field of logic.Or inference can be defined in another way. Inference is the non-logical, but rational, means, through observation of patterns of facts, to indirectly see new meanings and contexts for understanding. Of particular use to this application of inference are anomalies and symbols. Inference, in this sense, does not draw conclusions but opens new paths for inquiry. (See second set of Examples.) In this definition of inference, there are two types of inference: inductive inference and deductive inference. Unlike the definition of inference in the first paragraph above, meaning of word meanings are not tested but meaningful relationships are articulated.
