Krull Dimension

If $R$ is a Ring (commutative with 1), the height of a Prime Ideal $p$ is defined as the Supremum of all $n$ so that there is a chain $p_0\subset\cdots p_{n-1}\subset p_n=p$ where all $p_i$ are distinct Prime Ideals. Then, the Krull dimension of $R$ is defined as the Supremum of all the heights of all its Prime Ideals.
