A poll on ☞ Hacker News asking about what database does your startup use. The results at the time of this post show over 700 votes and MySQL and PostgreSQL leading. Anyways, NoSQL solutions like MongoDB, Cassandra, CouchDB, Redis are mentioned too.
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.
