not so hard to understand. :-)

This is a reasonable answer, but I want to offer a caveat.
Likely because of the influence of the originator of Ruby on Rails, it is close to holy writ in the web development community that the database must be treated as a dumb data bucket and all business logic must be implemented in the Ruby or Python or whatever back end code.
This heuristic is nearly always mostly wrong.

The accepted front-end developer wisdom of treating the DB as a dumb data store works under conditions, for example the DB will never be accessed from a different ORM / framework, and where the performance attributes of using an ORM with 'standard' datastructures are acceptable.
The moment you need to plug in something like reporting tools, or access from a different system / API / framework / language / ORM or whatever, the approach not having rules / views / procedures / whatever built into the database falls apart.
Other things to consider are performance / load / overhead: we have one system that involves processing through large amounts of data for reports / queries. Shipping all that back through the ORM / db interface (ODBC / JDBC / psycopg2 / whatever for resolution / filtering on the front end application where SQL / procedures / views could do that in the DB and just ship back the required data seems counterproductive.
