Architecture is a very simple module that gives you an overview of all the entities, taxonomies and variables found on your site. In form of a report, this information is intended to be easily readable documentation of how the site is put together.

Did you know about this module? It can come in handy if you wanna quickly check if a variable got saved by your module or what fields are in any of your entities. Although there is quite a lot of information already available in the three reports, Sheldon Rampton (the maintainer) would also like to include other stuff. A list of contexts, views, displays and features strike me as the most useful for the future.

But like I said, already if you look at the easily readable Variables report, you will like it - especially if you are a developer. The other two, namely the Entities and Taxonomies reports are interesting also to site builders because it allows them to quickly see what’s in there. Imagine you have a bunch of taxonomy vocabularies with as many terms, the Taxonomies report will give you a nice overview of what you have.

OK, so check it out and hope this helps.
