Most plugins have/use standard tables?

Hi All,

I’m researching different calendar plugins for a site we’re building. I’m not a techie. I’m guessing that most calendar plugins put their data in mysql tables in the main WordPress database?

For example a table name like: wpcalendar_eventdata_??? etc…

Or is it the case that some calendar plugins would not store their data in this way, but rather some other way that would make it difficult to read the data?

The project leader wants to be able to read the data put into the calendar plugin. I’m guessing if the plugin puts the data into standard mysql tables in the WordPress database, then it should be easy to read the data if we need to?

Let me know if my understanding is not correct. Thanks,
