ORM alternatives to ActiveRecord

To begin with this post in no ways undermines ActiveRecord. I am pretty happy with it, but for the sake of knowledge and to try a few options are there any other alternatives to ActiveRecord available? Has anybody used some开发者_StackOverflow社区 other ORM than ActiveRecord, if yes then which ORM is that? Please share your experience.

A place to look for ruby alternatives is https://www.ruby-toolbox.com/categories/orm , the listed alternatives are:

• ORM Adapter
• Sequel
• DataMapper
• Squeel
• Ruby Object Mapper
• Og

Another one to mention is Ohm, but only for Redis.
