In addition, or maybe this is also what typing and structure means, organizing data to eliminate duplicated or derived info and determining the keys or indexes needed to access it and the rules governing access and update: that’s half your app specification right there and how well you do it makes a big difference to the speed and flexibility of implementing the other half.
