摘要
An algorithm of exhaustive search of the 3NF relational schema, minimum from all equivalent schemes which are synthesized with Ling-Tompa-Kameda algorithm, is proposed. The reduction of search area is obtained owing to exclusion from examination the unkey attributes in subschemes of each equivalent schema. A polynomial time is necessary to find such attributes.
