Conclusion
Document databases store and retrieve documents and basic atomic stored unit is a document.  As always your requirement leads into the decision. You need to think about your data-access patterns / use-cases to create a smart document-model. When your domain model can be split and partitioned across some documents, a document-database will be a suitable one for you. For example for a blog-software, a CMS or a wiki-software a document-db works extremely well. But at the same time a non-relational database is not better than a relational one in some cases where  your database have a lot of relations and normalization.

Just check the following link from stackoverflow also to cover the pros/cons of Relational Vs Document based databases.
