Bitbucket Statistics (pull /merge/declined request) in database? where is data stored?

[Archie Gaw]

Hi, 

Is the information on the statistics for pull/merge request saved on some database for bitbucket? as I'm currently looking at trying to develop a report via tableau to show the statistics for out bitbucket.  but currently have no Idea how to connect to bitbucket to get the information? is there a way to connect to Database?

where are the data stored for bitbucket? I've read about connecting external database,

but not sure if i understand correctly.  if there is a external database connected, then the bitbucket data will be stored there and we can query against the tables? 

tableau supports some normal database types, hoping bitbucket will have a database like that .

thanks,

Archie
