 DVCS model is very attractive as a complementary tool to SCDB for the following reasons:
- * Ability to have the full history in its local environment makes easier to work disconnected to prepare changes.
+ * Ability to have the full history in its local environment makes easier to work disconnected to prepare changes. Despite a Git repository holds the full history, its size is significantly smaller than a SVN repository holding the same information.
  * It's possible to work on some changes with the advantage of versionning, without publishing them in a central repository, until there are ready or just throwing them away if you change your mind.
  * By design, ''branching'' and ''merging'' are very easy and efficient in DVCS: this allows to work on several changes in parallel, with the ability of commit incremental changes and merging them in the main branch, the one to be deployed, when they are ready.
  * Some DVCS, like [http://git-scm.com Git], allows to easily pack together a set of revision into only one. This allows to keep a cleaner history in main branches when doing incremental development.
 
-A feature present in many DVCS is the ability to be used to mirror a SVN central repository and act as a replacement of the SVN working copy. One command allows bi-directional synchronization between SVN and the DVCS repository. In [http://git-scm.com Git], this is provided by `git svn` command.
