It all depends in your case it is probably better not to go the SP route and do everything the DDD way (make a Domain model in code and use that).

Two suggested best practices from experience:

[A.vim](http://www.vim.org/scripts/script.php?script_id=31) is a great little plugin. It allows you to quickly switch between header and source files with a single command. The default is `:A`, but I remapped it to `F2` reduce keystrokes. |
