The main difference being ArangoDB's flexibility and functionality when working with graph data. written by which author, you can use edge collections. If multiple documents are linked with the entity, it is not guaranteed that the same document is returned every time. Moreover, different models can be combined in a single query. We will now use impractical to change each and every user document if this numbers changes. If you also want to query which books are written by a given author, embedding authors Oasis provides fully managed, and monitored cluster deployments of any size, with enterprise-grade security. Interpreting the [Fowlers] basic idea leads us to realize the benefits of using a variety of appropriate data models for different parts of the persistence layer, the layer being part of the larger software architecture.
