Are tables/entities in Atlassian Analytics comparable to the database in Data Center?

[Matteo Vecchiato]

Hi community,

I'm investigating about the necessity to build a complete export of Jira/JSM projects and work items through Atlassian Analytics.

The data that can be extracted with Atlassian Analytics are comparable to what I can extract with a sql query from Data Center ?

What kind of data is not possible to extract from Analytics?

Thank you for any help
