 * If using the database engine “MyISAM”, case sensitivity of database and table
   names can vary on different Operating Systems and based upon the MySQL configuration.
   REF: [http://dev.mysql.com/doc/refman/5.5/en/identifier-case-sensitivity.html](http://dev.mysql.com/doc/refman/5.5/en/identifier-case-sensitivity.html)
 * If using the database engine “InnoDB”, on Windows it always uses lowercase database
   and table names (irregardless of the MySQL configuration). REF: [http://dev.mysql.com/doc/refman/5.5/en/innodb-restrictions.html](http://dev.mysql.com/doc/refman/5.5/en/innodb-restrictions.html)
 * WordPress (and most database installation tools) will use the default database
   engine configured by the database server (unless requested otherwise). As of 
   MySQL 5.5, the default database engine is InnoDB. REF: [http://dev.mysql.com/doc/refman/5.5/en/innodb-default-se.html](http://dev.mysql.com/doc/refman/5.5/en/innodb-default-se.html)
 * WordFence uses camelCased tables names. Doing so complicates any database export/
   import between different database servers as case sensitivity regarding database
   and table names is not guaranteed consistent (even from UNIX to UNIX). I would
   strongly recommend future versions of WordFence use snake_case names (or all 
   lowercase names) to avoid complications.
 * In addition to server migration (from an old server to a new server), people 
   maintaining separate “live” and “development” servers to allow for testing without
   impacting the “production” website are also impacted by the use of camelCase 
   table names.
