>>The Wikka installer creates some tables necessary for storing Wikka data. 

Note that they have the prefix you chose in the install process. For example:  if you chose prefix: ##""MyWikka_""## (stored in ##[[ConfigurationOptions | wikka.config.php]]##), ##$this->config["table_prefix"]."pages"##  will result in a MySQL table named ##""MyWikka""_pages##.

All of the tables have the type [[http://dev.mysql.com/doc/mysql/en/MyISAM_storage_engine.html | MyISAM]].

The tables presented below use the default ##wikka_## prefix:

~- a version is identified by a unique ##id##,
