I want to make a database but don't know at all how to do one. I've looked at some tutorials but they just show me how to sort a bunch of data very loosely.

The picture below is what I've made so far. The top boxes are the main data and the box below (next to "DC") is the place where the file name will go. I want to enter the file name and I want all the data above to fill in for what I've saved it for. Then I want to go and insert another DC file name and it brings up data associated with that file.is it possible to save information and pull it up again like this?
