Wikibase uses a SQL database, like other MediaWiki extensions. My understanding is that it implements a few additional types of pages, like Item and Property. This SQL database can be accessed fairly directly [https://wiki.personaldata.io/wiki/api.php through the API]. You can read and write through this API. However in order to use [[Help:SPARQL]], this SQL is fed into a Blazegraph triplestore, thanks to the ''updater'', which runs at (ir)regular intervals. '''It is very important to understand that the information goes one way and only one way from the SQL database to the Blazegraph database'''. From there the data can be [[Help:Query|queried]] in different additional ways.
