MongoDB’s flexible schema allows for multiple patterns when it comes to modeling relationships between entities. Also, for many use cases, a denormalized data model (storing related data right within a single document) might be the best choice, because all information is kept in one place, so that the application requires fewer queries to fetch all data. However, this approach also has its downsides, such as potential data duplication, larger documents, and the maximum document size.

In general, MongoDB recommends using normalized data models when the advantages of embedding are neglected by the implications of duplication. In this blog post, we take a look at the different possibilities of linking documents with manual references and DBRefs…
