The primary database for all test result data is BigQuery. The dashboard, https://wptdashboard.appspot.com/, does not query BigQuery directly. Instead, we generate a datastore entry for each test file (e.g. html/semantics/forms/the-input-element/date.html) that contains the latest results for all browsers.

The data currently in the dashboard was generated by a Python script directly querying jgraham's sqlite file. Now that all jgraham's data has been loaded into BigQuery, we should generate the data from there.
