According to Paul Smith, who has an AMA about healthcare.gov at Lobster.rs[0], the database was MarkLogic, which started out as an XML database, according to its Wikipedia page[1] (Paul also mentions this briefly his 10th anniversary post). According to another commenter[2], who says he met a MarkLogic manager on a plane flight, MarkLogic had passed some sort audit/certification that only Oracle had previously passed, which may explain why it was used for healthcare.gov.
