Speak the Language of Data Visualization with Tableau Terminologies

Tableau is used for data visualization and business intelligence tool that allows users to create interactive dashboards, charts, and maps to analyze and understand data. Here are some common terms used in Tableau:

1. Dashboard: A dashboard is a collection of interactive charts, maps, and other visualizations that provide an overview of data.
2. Worksheet: A worksheet is a single chart or visualization that can be added to a dashboard.
3. Data source: A data source is a file or database that contains the data that is used to create visualizations in Tableau.
4. Dimensions: Dimensions are data fields that are used to categorize or label data. For example, a “Category” dimension might include values like “Clothing,” “Electronics,” and “Home Goods.”
5. Measures: Measures are data fields that contain numerical values that can be aggregated or calculated. For example, a “Sales” measure might contain values like “100,” “200,” and “300.”
6. Filters: Filters allow users to narrow down the data that is displayed in a visualization by specifying certain criteria. A filter, for example, could be used to only display data for a given time period or region.
7. Parameters: Parameters are values that can be used to dynamically control the data that is displayed in a visualization. For example, a parameter might be used to allow users to choose the time period that is displayed in a chart.
8. Calculated fields: Calculated fields are new fields that are created by applying calculations to existing data fields in a data source.
9. Hierarchies: Hierarchies are sets of related dimensions that can be used to drill down into data at different levels of granularity. For example, a “Date” hierarchy might include year, quarter, month, and day levels.
10. Groups: Groups are sets of related dimensions that can be used to combine similar data values into a single value. For example, a “Region” group might include “North,” “South,” “East,” and “West” as individual values.
11. Live connection: A live connection is a direct link to the data source that allows Tableau to access the data in real-time.
12. Workbook: A workbook is the main file type in Tableau that contains one or more worksheets. A workbook contains all the visualizations, dashboards, and data connections created by a user.
