Yes, once I get everything written out, I will go back to restructure the tables; however, I don't know how in-depth these tables will be. A table may only have one or two columns in it.
E.g. - Stems Table - Column 1 (What stems) - Rows 1-#X will be the different stems available.
Or I could lump everything into one table (All Parts) and have as many columns as necessary (Series, Stems, etc). Then in the respective columns, the rows will house their parts.
In your opinion, which is the better route? With one table, I'll only ever have to call on one table. However, it will be one very large table.
