A First Web Project with Clojure

Last nights GatorJUG prestation on Clojure with Eric Lavigne introduced us to Clojure's language elements. Say your customer, a timeshare company, wanted a new database driven reservation website. Build a case for Clojure and lay out a reasonable architecture, including use of existing Java components and object relational mapping, or not.

If I offered to finish the site in a week, would my client need further justification :-)

A timeshare reservation site would be fairly trivial from a technology perspective. For the web front-end, I would use Compojure, just as I did with the Wari contest. For database access, I would use clojure.contrib.sql, which has the same capabilities as java.sql but without being so incredibly verbose.

Architecture is important for big projects. This isn't a big project.

So, Eric - can you say a few words about Compojure? Just enough to get us started. And, please point us to a reference. Is clojure.contrib.sql fairly full featured? Can it to stored procs and transactions? What are some of its strengths and limitations? Just a taste...

Compojure is a web development library with a focus on simple, RESTful applications. This example should give you a feeling for Compojure:

And here are some references:

You can find some examples of clojure.contrib.sql here:

And here's a reference:

http://richhickey.github.com/clojure-contrib/sql-api.html

clojure.contrib.sql has transactions and prepared statements. I don't know about stored procedures, since I have never used them in Clojure or Java.

Driving and Measuring the Impact of Platform Engineering

Platform engineering has to be approached from a socio-technical perspective, and shaped by all stakeholders, not just developers, Sergiu Petean said in his talk Driving the Future of Insurance through Platform Engineering. Platform success depends on written principles that endure change while embracing change as the main design force, to enable teams to build, run, and release software.
