What Tableau is and where things live

• Tableau turns data into charts and dashboards. Most companies use Tableau Cloud in the browser: sign in at online.tableau.com with your work account. Tableau Public is free, but anything you save to it is public.
• Your site role sets what you can do. A Creator connects to data and builds, an Explorer builds from data already published, and a Viewer looks and interacts. Find yours under your profile icon > My Account Settings.
• Explore lists the projects, workbooks and data sources you can open. A workbook is a file of sheets, and a sheet is a worksheet, a dashboard or a story. A data source is Tableau's connection to your data, such as a table of orders.
• In a worksheet, the Data pane on the left lists fields. Dimensions are labels like Region, Product or Order Date. Measures are numbers like Sales, which Tableau adds up and shows as SUM(Sales).
