I think instead of spending time in decision making about what to use whatnot, ect. Why dont you use a system like Najim posted in his reply in the thread you posted. I am sure he will provide you with it. And you can concentrate on collecting the data.
Access 2003 , One Table, create Autoform, Keep adding Data, create AutoReport..Simple can be done in 2 mins. obviously enetering data will take time…So think bout it…
Using Java + XML or dotNET + XML is another option if you don't prefer professional database systems. It requires a bit work, but it takes the minimum resources and minimal cost. All you will need is a system with JVM or dotNET framework installed on it (both available free of cost) and your programs and resulting XML files. XML data can be converted to any professional database system later (if rerquired). If you can post details about your data here, I can post associated codes.
