Where to start?
I use Mathematica extensively to do data analysis and modeling.
But I have never used Mathematica for data entry. Once I get the
data in some electronic format, I typically use a text editor to
format the files as a Mathematica expression putting comments at
the start of each data file. That is the structure of the files
are typically:
(*
comments

{
{field1, field2 . .... fieldn},
