基于超图的关系模式到2NF的分解
Decompositions for Relational Schema Based on Hypergraph Into 2NF
-
摘要: 本文利用超图讨论了关系模式到各级范式分解的新的基本理论。提出了基于超图的关系模式满足2NF 的新的判定定理和到2NF 的模式分解算法。Abstract: A new fundamental theory on relational schema decompositions is discussed by hypergra- ph.The new decision theorems of relational schema based on hypergraph satisfied 1NF,2NF and the algorithm for decomposition to 2NF are mentioned.
