As a first time reader of these docs, they don't seem at all approachable. For example: for the quickstart, the premise is simple - show me quickly how I can create a class, map it to the database, create some examples, and delete them. Something like what mongoose does here: https://mongoosejs.com/docs/ https://mongoosejs.com/docs/ Instead, SQLAlchemy goes from how to declare models (with a wall of code followed by a wall of text), jumps into creating "engines", shows some generated SQL code for creating tables, and so on. Sessions are simply used without being introduced, and many questions arise - am I hoarding a database connection as long as I am holding onto the session? Why should I do anything other than executing queries while that is happening? Then that means the `with` expression is useless, unless I want to explicitly run a multiple-query transaction - but why should this be the default? It also comes across as clunky to be importing a `select` statement at the top level. Why not call select on the table objects themselves? And what's up with `select(...).select_from(...)`?
