1.high speed memory that is built into CPU for storing temporary instruction
and data is called?
答案是cache，我想请问为什麽不是register呢?
2.*A normalize DB stores non-primary key data in only one location.
*Normalized DB have a design that reflects the true dependencies between
tracked quantities.
这两句话到底是什麽意思呢?
