JazzRecord is ActiveRecord for JavaScript (ORM)

ActiveRecord is a popular object-relational mapping layer for Ruby that provides an easy means for dealing with database tables, complex relationships between data models, and error validation. It’s a powerful, yet accessible library. JazzRecord is a free and open-source JavaScript ORM that seeks to minimize its learning curve by mimicking ActiveRecord style and conventions.
