With DAO you are building a refinery- you look at what comes through, how long it takes to process, how its stored and where your pipe has the smallest diameter and what distillation unit takes the longest. With Object Orientation you will do the same, but with n different typed bottles in boxes, the boxes in containers which are driven around as a whole by trucks. You might be able to do so in great comfort - everybody on this planet knows how to ship boxes. But you will trade off for control and efficiency.
