传递依赖
如果我有以下关系:
Staff(staffNo(PK), sName,position,salary,branchNo,branchAddress)
可以公平地说,staffNo -> > BranchAddress 是传递依赖,如 StaffNo ->分支号和分支号-> branchAddress
抱歉,我正在复习考试,传递依赖关系让我有点不舒服……
If I have the following relation:
Staff(staffNo(PK), sName, position, salary, branchNo, branchAddress)
Is it fair to say that staffNo -> branchAddress is a transitive dependency as staffNo -> branchNo and branchNo -> branchAddress
Sorry, I'm revising for an exam and transitive dependencies are throwing me a little...
