We introduce the concept of Semantic Comment which is incorporated into the elements of the Database. Syntaxdiagrams are established for the common operations of Selection,Projection and Join. In practice the Semantic Comment incorporates themeaning of all the elements in a Database System. The SemanticComment will help in the creation of ontology starting from a RelationalDatabase System. The table storing the Semantic Comments will behelpful for the optimization in answering new queries.
