I wish suggest you to look for a book that is not limited to sql, and
starts from very general aspects, such as real world modeling (as
entity relationship diagrams), concurrency, integrity, and talks also
of not sql and not relational databases. SQLAlchemy is a object relational mapper, you can think SA as a easier way to access your SQL database, but it's also, from the application view, an object oriented database, that use sql because is simpler reuse many good sql implementations around to have persistence, concurrency control, management tools etc. I learned database on a rather old book, Principles of Database and Knowledge-Base Systems, of Jeffrey Ullman, and perhaps is too much academic, but gives you a very large view of databases. At my advice you can search something of newer that talks not only about relational but also about object oriented databases. Ezio Alexandre CONRAD wrote:
