摘要:
本文给出了关系模型中关系模式属性间函数依赖概念的另一种定义,该定义是根据集合论得到的。对于这一点,证明了一个定理,建立等价性和基础定理的算法是建立在属性之间的功能依赖搜索。通过一个具体的例子说明了该算法
英文摘要:
An alternative definition of the concept is given of functional dependence among the attributes of the relational schema in the Relational Model, this definition is obtained in terms of the set theory. For that which a theorem is demonstrated that establishes equivalence and on the basis theorem an algorithm is built for the search of the functional dependences among the attributes. The algorithm is illustrated by a concrete example
