Workbooks and sheets: Tableau uses a WORKBOOK and SHEET file structure, much like Microsoft Excel. A WORKBOOK contains SHEETS, which can be a WORKSHEET, a DASHBOARD, or a STORY. A WORKSHEET contains a single view along with shelves, legends, and the Data pane. A DASHBOARD is a collection of views from multiple worksheets. A STORY contains a sequence of worksheets or dashboards that work together to convey information.
