What you want is usually called ORM: Object-Relational Mapping, which
is a way to map data from a database into objects in a programming
language. In Ruby there are several implementations, you should check
some of them and choose one that suits your project. The most popular
ones (as perceived by me :slight_smile: are ActiveRecord, Sequel and DataMapper.
You can use google to find documentation about those.

Hope this helps,

Jesus.
