Many languages provide database abstraction to save data (objects) to relational databases (generally through object relational mapping (ORM)).
I'm aware that Julia is not a "conventional" object oriented language (see julia: OOP or not )
But I wonder if a library with the following features exists ?
Connect to a database through a database URI like
"dialect+driver://username:password@host:port/database"
(see Python SQLAlchemy http://docs.sqlalchemy.org/en/latest/core/engines.html )Store objects (in fact instances of composite type) to a DB
Retrieve objects from DB
