Take a piece of paper and make a simple shopping list: one column for the items you need and one column for the number of items you want. Did you just create a database? I think you did: you can sort it and find items in it, you can cross-reference items in the store’s price list, which makes it a relational database, and you can add it to a longer list of all the shopping you’ve ever done. OK, so it’s not that fast or efficient, but it has data organized in fields and records.
