The decomposition algorithm for 3NF ensures the preservation of dependencies by explicitly building a schema for each dependency in the canonical cover. It guarantees that at least one schema must hold a candidate key for the one being decomposed, which in turn ensures the decomposition generated to be a lossless ... aquamira tactical frontier pro ultralight filter WebI am trying to make sense of an example of 3NF decomposition using the 4-step algorithm mentioned by Ullman here, but I'm not understanding what my lecturer is doing with the last step (or, worse, I'm not understanding the algorithm itself)..
