Document Database vs Object Oriented: Structural Storage Format

The key difference between a document database and an object-oriented database is in how the data is stored. Document databases store data in a structural type format, like binary type things, behind the scenes. This means that data is not stored as a JSON document and collections are stored differently. In contrast, object-oriented databases store data in a different way, not by crushing the model into a single document. The structural format of storage in document databases is a significant differentiator between the two.
