If logical query is ambiguous then physical query is ambiguous. Logical independence is achieved through the unambiguous query . Unambiguous query designed through Steiner tree and the cost function.. Different queries are occurred for the same information. The best logical query is achieved through the cost function. In this paper unambiguous logical queries are designed through the Steiner tress and cost functions and Blockchain system is discusses using Steiner trees for physical query independence. Some examples are given for these problems. Keyphrases: Physical Design, Steiner trees, conceptual design, query language
