What the chart shows

The database demand chart captures three eras in one picture. MySQL leads the early years, the NoSQL wave lifts MongoDB to a real share in the mid-2010s, and Postgres steadily climbs to become the default relational choice teams reach for now. Redis rides alongside as the near-universal cache, while Elasticsearch, Cassandra and DynamoDB hold specialist slices. Read the relative bands to see the lead change hands era by era, and the sample postings to see which databases each stack pairs - Postgres with Python and Django, MongoDB with JavaScript, Redis with almost everything.
