I've argued for a long time that everything in programming comes down to:

1. Data. It can be in many different forms and structures, more or less strictly typed, and a big part of writing a program is determining what it looks like, and what it should look like.

2. Procedures to work on that data. They can transform the data, remove it, reshape it, convert it, or do any number of other operations on it, simple or complex.

That's all there is to programming.
