The Syntheses of the Decomposition of Relational Schema: A Further Study
In this paper, the syntheses of the decomposition of relational schema is studied more deeply. The condition that relational schema is enanged into BCNF, 4NF, 5NF by the syntheses, and has "the preservation of FDs" and "lossless join" is mentioned.
