## Create the App with a Single Model

We'll create the simplest first version of the app with a single **SQLModel** model first.

Later we'll improve it increasing security and versatility with **multiple models** below. 🤓

Some compiler optimizations that would be valid in single-threaded programs are not valid in all Go programs.
In particular, a compiler must not introduce writes that do not exist in the original program,
it must not allow a single read to observe multiple values,
and it must not allow a single write to write multiple values.
