  • Schemaless SQL — The Best of Both Worlds

    by Will Leinweber

    Schemaless database are a joy to use because they make it easy to iterate on your app, especially early on. And to be honest, the relational model isn't always the best fit for real-world evolving and messy data.

    On the other hand, relational databases are proven, robust, and powerful. Also, over time as your data model stabilizes, the lack of well-defined schemas becomes painful.

    How are we supposed to pick one or the other? Simple: pick both. Fortunately recent advances in Postgres allow for a hybrid approach that we've been using at Heroku. The hstore datatype gives you key/value in a single column, and PLV8 enables JavaScript and JSON in Postgres. These and others in turn make Postgres the best document database in the world.

    We will explore the power of hstore and PLV8, explain how to use them in your project today, and examine their role in the future of data.

  • Rails: The Next Five Years

    by Yehuda Katz

    When Ruby on Rails burst onto the scene in 2004, it excited web developers by showing that you could build next generation apps quickly and efficiently. Rails was one of the first frameworks to embrace Ajax, giving everyone the power to do partial page updates and whiz-bang effects in a conventional, effortless way.

    In 2007, the Rails team embraced RESTful conventions, making API development a no-brainer for new applications. Because RESTful JSON is so easy in Rails, Rails applications tend to implement APIs on balance.

    Then it was time to polish. Both the 2.0 and 3.0 releases cleaned up the code-base and found ways to take emerging conventions and make them easier to use.

    But now, like in 2004, another revolution is brewing. Increasingly, developers are moving their view layer from the server into the client, using RESTful JSON and client-side templating to increase responsiveness and bring applicable aspects of desktop applications to the web.

    Like last time, not every application needs to jump head-first into this new world. But just as in 2004, Rails has an opportunity to embrace the future, and bring its ruthless insistence on convention over configuration to bear on this problem.

    Rails already has the plumbing to be a fantastic conventional JSON server. The question is: will we take the challenge, or will we desperately cling to the past, hoping that the future will never come?
