A entity with active record, is a object or a component?

A entity with activ开发者_StackOverflowe record is a object or a component?

I agree with Jeff Sternals comment on your question; but the short answer is probably "yes" - in that an entity with an active record would be an object - it won't be a component.

In my experience: a component is usually a specific sub-system or part of a solution that has a clearly defined interface and which can be re-used in multiple solutions.

I'd also suggest that a component isn't something that would typically be used as a stand-alone system; a component is something like an engine or chassis, unlike a car or truck which would be a complete "system".

So a component is an architecture concept - entities and objects are concepts that exist more at the code / design level.

Also Entity can have different meanings depending on the context.
