Arel is a Relational Algebra for Ruby. It 1) simplifies the generation complex
of SQL queries and it 2) adapts to various RDBMS systems. It is intended to be
a framework framework; that is, you can build your own ORM with it, focusing on
innovative object and collection modeling as opposed to database compatibility
and query generation.
