The Database Database

What it does

There are at least 300+ databases out there, and they all do something slightly different. The Database Database breaks down popular databases like Postgres and Elastic and explains them in simple, clear language.

A database of popular databases that your developers are using, organized by purpose and type.

A table of major databases and what they're used for, explained in clear and easy to understand language. Click on a column header to sort (once for ascending, and twice for descending). To learn more about different types of databases and what they're used for, check out The Beginner's Guide to Databases here . Fun fact, the data in this table is actually stored in a database in the cloud. PostgreSQL on Supabase to be exact. Is there a database not on the list that you'd like to see explained?

  Talanoa▲345

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT▲688

  I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
