Would a model like this translate well to a document or graph database?

I’m trying to understand what types of models that I have traditionally persisted relationally would translate well to some kind of NoSQL database. Suppose I have a model with the following relationships:

Generating documents from a graph data structure where each document represents a Node in the Graph

Does it make sense to use a graph database (Neo4j) for a diagramming app?

I am developing a diagramming application and want to optimize operations with the Nodes and Relations of the diagram. Currently, I am using a relational database with tables for diagrams and nodes. Each node entity has a field children containing the IDs of its child nodes, which forms the relationships. This architecture seems far from ideal to me, so I am curious whether I would gain a performance boost in operations with the diagram elements by using a graph database. I am referring to operations such as retrieving all nodes for a specific diagram, modifying nodes, relationships, etc.

Would it be bad to use two different database engines for location history?

I’m building an analytics and storage platform for entity location history. I’m a bit hung up on the database engine, though. On the one hand a graph database fits really well for the entity relationships. On the other hand, queries around the time based dimension (e.g. entity history and the history of a defined area) seem to fit better in an RDBMS.

How does I/O work for large graph databases?

I should preface this by saying that I’m mostly a front end web developer, trained as a musician, but over the past few years I’ve been getting more and more into computer science.

Designing a social network with CQRS, graph databases and relational databases in mind

I have done quite an amount of research on the topic so far, but i couldn’t come up with a conclusion to make up my mind.

Which approach would be better for persisting these overridable configuration keys and values? A simple key-value store, or a graph database?

I’m creating a system where there are config keys and values. So for example:

How can I model this scenario in a graph database?

I’m developing an application where users can tag resources and it’s also important to know who tagged the resource with a specific tag.
