DECODE returns alternative values based upon what is return. For example, if "A" or "T" is returned from the query, "Active" or "Terminate" could be displayed. REPLACE replaces character strings within the return value with an alternative character string, or optionally NULL. so that REPLACE('Hello Fred',' ','') becomes HelloFred.
