Building data products with Python

The following is a repository containing the code for a wine reviews and recommendations web application, in different stages as git tags. The idea is that you can follow the tutorials through the tags listed below, and learn the different concepts explained in them. We will use Python technologies such as Django, Pandas, or Scikit-learn. The tutorials also include instructions on how to deploy the web using a Koding account.

About Java project and package organization

There is a heated debate about what is the most appropriate organization and naming convention of Java packages and projects and, by extension, software modules. The two approaches are ‘by abstraction layer’ (e.g. model, controller, view, etc) or ‘by feature’ (e.g. account). I find that, at least at an inside-tier level (e.g. application level), the later approach makes more sense. That is, a tier will be contained in a project (e.g. web-service or core) where packages are organized by features. Inside of these packages I reproduce the different abstraction layers in sub-packages if needed.

Enterprise Integration vs Distributed Systems
