Object vs Document Storage (Databases) = Difference (nosql)?

Question

i would be thankfull for a short explanation of these different concepts. Wikipedia mentions both in context of NoSQL but I did not find any further information whats the difference between both.

Update regarding the comments:

http://en.wikipedia.org/wiki/NoSQL#Object_database

vs

http://en.wikipedia.org/wiki/NoSQL#Document_store

But the difference is completely unclear to me. (Stackoverflow does not allow me to post two links as newbie so the links are actually disabled)

Thanks Jens

Answer 1

For most practical purposes, there is no difference - A document is often just a serialized object, and if you only need basic storage, any key/value store can hold objects.

There may be differences in things like how partial updates and queries are handled, but since there is no such thing as standard NoSQL, you get just as many differences between products in the same category.

Answer 2

"S3 is an object store ... DynamoDB is a document database" They go into some detail about the differences here: https://serverless.pub/s3-or-dynamodb/
