title: Where does Subversion physically store its DataBase?
body: <p>After reading many introductions, starting guides, and documentation on SVN, I still cannot figure out where is my versioning data stored. I mean physically. I have over <em>EDIT</em> [1/2 GB] of code checked in, and the repo is just a few MB large. This is still Voodoo for me. And, as a coder, I don't really believe in Magic.</p>
  
  <p><strong>EDIT :</strong> 
  A contributor stated that not all the code was stored in the repo, is that true ? I mean, if I delete my local working copy I still can get back my source code for the repository...
  If so, I still can't understand how such a compression can occur on my code...</p>
  
  <p><strong>EDIT 2 :</strong> 
  When I import the code into repository I have the message "50MB uploaded" and the actual repo is much smaller. Compression Algos must be involved.

  <p><em>BTW, It's funny to read some answers and see how many people DO Indeed believe in Magic, and use SVN without REALLY Knowing what goes on behind the scenes...</em></p>
