In our talk we’ll provide an overview of system functionality and scale, and show how several key aspects of the system were implemented using Ruby on Rails and other open source technologies.

Given the size of this project, we faced challenges that don’t come up in most Rails projects, such as managing 700 database migrations, and transforming and importing large volumes of legacy data. We will discuss areas where we found Rails worked well for a larger-than-average project, and areas where we had to be a bit creative in order to make things work.

In particular, we’ll focus on

  • how we implemented fine grained authentication and authorization on controller action and object level
  • how we managed large scale data migration issues by task parallelization using a self built computing grid
  • how we leveraged Rails technologies, gnuplot and Latex to build a flexible reporting system

Various concerns are often raised concerning the adoption of Rails in the enterprise — performance, (un)availability of experienced ruby programmers, risks associated with using a dynamic language, etc. Often these discussions miss the real benefits (and risks) of adopting Ruby for a complex enterprise project. Through this case study we hope to shed a little light on this subject.
