 * I develop a WordPress plugin, which has several database tables of its own. The
   plugin creates these tables when activated, and removes them when deleted/uninstalled.
 * I have to implement an update process of the plugin which updates plugin’s code
   as well as tables structure. The simplest case would be to add a new column to
   one of the tables. The more complex case would be to create a new tables structure
   and update the content accordingly.
 * How would you recommend to solve this problem? Is there any built-in WordPress
   functions that may help?
