There are two camps within our ranks: the first camp believes the front- and back-end should be completely separated, where both applications have separate version control, build processes, and deployments.
Disclaimer: I'm in the camp that believes strongly in separating the two. So I want to argue the case for separating front- and back-end completely in the post.

Aggregation operations group values from multiple documents together, we can perform a variety of operations on the grouped data to return a single result. Spring Data Mongo makes the usage of this feature from your Java application very easy.
