They certainly have other uses. Models represent any domain object that you need. Sometimes these objects will correspond to DB records, sometimes not. > > Models descend from ActiveRecord::Base. That certainly gives rise to > a notion that models are used exclusively with databases. [...] The Rails community often gives the impression that models have to descend from ActiveRecord::Base, but that's only true *if you need ActiveRecord features*. True, most models in Rails apps tend to inherit from AR. However, if you're modeling something that doesn't interact with the DB, there's generally no need to inherit from AR, but the class is still a model because it represents a domain object. In other words, whether a class is considered a model has to do with the *conceptual* niche that it fills within the app, not with whether it inherits from AR. Does that help?
