You say you have to maintain Milk collection database... does this mean you have a database you could upload?
I have developed a lot for the dairy industry, so I would like to see if I can help!~)
Here's an example that's very simple an keeps all the data in a de-normalized form which I think is the best for this little project!~)
..if you want to do any changes then remember to hold down shift when you open the database.
