SVN was a good enough version control system (VCS) and sometimes even a synonym for VCS in everyday talks. However, technologies change and the way of developing computer software as well, in my opinion, SVN became some kind of “disturbing” or “breaking” thing in development process.

It has a bit different logic, but you can get used to it relatively quickly without any problems.

Unfortunately, Magento doesn’t to remove them through admin panel, so you will not find any button “Delete Order”. This may frustrate you as a developer and your client. The fact that the ordering data is stored in different database tables (sales, warehouse, etc..)
