Report Builder, or "new style reports", replacing legacy reports (in reportdesign). Started as an extension called "Sun Report Builder" then "Oracle Report Builder" [http://extensions.services.openoffice.org/project/reportdesign], which got bundled with LibreOffice, then converted to an optionally installable (but installed by default) part of LibreOffice proper. Uses the Pentaho Reporting Flow Engine of Pentaho BI [http://www.pentaho.com/].
