Let's say I have the table:
M1 M2 M3
S1 S2 S1 S2 S1 S2
P1 D1 T1 0 1 2 3 4 5
P2 D2 T2 6 7 8 9 10 11
P3 D3 T3 12 13 14 15 16 17

How can I make it so that the table becomes partially normalized, like:
M1 M2 M3
P1 D1 T1 S1 0 2 4
P1 D1 T1 S2 1 3 5
P2 D2 T2 S1 6 8 10
P2 D2 T2 S2 7 9 11
P3 D3 T3 S1 12 14 16
P3 D3 T3 S2 13 15 17
Do I have to first merge the two headers, and then normalize + split values?
Further explanation:
becomes partially normalized, like means that the table isn't completely normalized, like:
Data
P1 D1 T1 M1 S1 0
P1 D1 T1 M1 S2 1
P1 D1 T1 M2 S1 2
P1 D1 T1 M2 S2 3
P1 D1 T1 M3 S1 4
P1 D1 T1 M3 S2 5
P2 D2 T2 M1 S1 6
P2 D2 T2 M1 S2 7
P2 D2 T2 M2 S1 8
P2 D2 T2 M2 S2 9
P2 D2 T2 M3 S1 10
P2 D2 T2 M3 S2 11
P3 D3 T3 M1 S1 12
P3 D3 T3 M1 S2 13
P3 D3 T3 M2 S1 14
P3 D3 T3 M2 S2 15
P3 D3 T3 M3 S1 16
P3 D3 T3 M3 S2 17
merging the headers would be having a single header cell with the value of M2_S1 for example, after merging the headers it's rather trivial to normalize. However one would need to split the value of those header cells, as in M2_S1 to M2 and S1.
I am expecting an answer in the form of pentaho-spoon steps, and an explanation of what is being done and why it is being done in each step.
