: I think the nontrivial perhaps means that process of DM does not equal the 
I think non-trival means datamining needs iterative process.
Preprocess,mining and evaluate patterns are iterative.
When we found out some patterns,perhaps the patterns are not
so good.So we need to preprocess again,mine again and evaluate
again.Until the result can satisfy us.

: simply query through the database to seek knowledge, it need more steps 
: and more skills.
