About a week ago, I posted about Sadie, a construct for optimized data access and analysis, and Olsen, a simple reporter that makes it easy to produce typeset reports (among other data products) using a framework of very manageable data primers and a powerful templating system that marries ruby’s erb templates with sadie’s data access api.

Both gems have seen several revisions since then and I’ve written an article to give an overview of both projects with some code to show how simple they are to use.
