True, but MongoDB is flexible for changing data structures. Still, I prefer MariaDB.

I keep mixing up the types of databases, but I think an in-memory database like memcached wouldn't work for storing persistent client and order data.

The messaging service option doesn't seem relevant here. We need to store and query the client and order data, not just pass messages between systems.

I'm leaning towards the NoSQL database as well. The requirement to associate each order with an existing client makes me think a document-oriented database would be a good choice.

A relational database like MariaDB could also work, but it might be overkill for just storing client and order data. The NoSQL option seems simpler.

I feel like we had a practice question about client-order relationships, and I think it pointed towards using a relational database for that.

I'm not entirely sure, but I think NoSQL databases like MongoDB might not enforce strict data types as well as relational ones do.

I'm a bit confused on the difference between an object store and a NoSQL database. Can someone clarify which one would be better for this use case?
