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. Within a workbook, you can create new sheets, clear an entire worksheet, duplicate sheets, hide or show a worksheet, and delete a sheet. Tableau has several ways to view and organize the sheets in your workbook. NOTE: From worksheet we can access Source Data Dimensions, Measures, Custom Fields. From Dashboard we can access Worksheet but we can not access dimensions measures directly. From Story we can access Dashboard and Worksheets but we can not access dimensions measures directly.
