This shouldn't be hard to understand. There are always trade-offs in
design. For a single user database you wouldn't have to worry about
locking at all or could use something simple like a total database level
lock or table level locks. This will win for single users or low
concurrency needs *but* try it when you have many users or have a high
concurrency use and the coarse-grain locking will fall on its face.
