When prototyping an application it’s common to need to change the database frequently and MongoDB allows me to do that without the need of generating migrations and keeping the DB schema in the model layer.
You can use a document database at least until you nail your model.
This blog is called myNoSQL and it is written by me, Alex Popescu, a software architect with a passion for open source and communities.
It records my readings, learnings, and opinions on NoSQL databases, polyglot persistence, and distributed systems -- subjects that I'm passionate about.
The opinions expressed here are my own, and no other party necessarily agrees with them.
If you feel I'm biased, I probably am.
