Introduction

Object-relational mapping (ORM) provides developers with a set of tools that ease management of the relationships between objects and relational databases, thus allowing applications to be easily extended to add data persistence. For Ruby, several object-relational mapping options are available. This wiki concentrates more on the comparison of ORMs and provides a high level overview of the top Ruby ORMs: ActiveRecord ,Sequel and DataMapper. It also includes a minor discussion on alternative frameworks that can be used either in place of or along with ORMs. These include the persistence framework iBATIS (more specifically the Ruby version RBatis).
