Tableau is a powerful business intelligence and data visualization tool allowing users to examine, analyze, and share data meaningfully. You must understand the fundamentals of Tableau to fully utilize it, whether you are a data analyst, a company worker, or a decision-maker.
A Quick Overview of Tableau
Tableau was founded in 2003 as a consequence of a computer science project at Stanford that sought to enhance the flow of research and make it easier for individuals to access data.
VizQL, Tableau’s primary technology, was created and invented by Chris Stolte, Pat Hanrahan, and Christian Chabot. VizQL visualizes data by converting drag-and-drop actions into data queries via an intuitive interface.
What is a Tableau Workbook?
A Tableau Desktop worksheet, dashboard, or story is saved in a file called a “workbook.” It is the primary document used to make projects in Tableau for analyzing and displaying data.
What are Tableau Filters?
Filters are one of Tableau’s most critical components. They allow consumers to control and filter the info they see. Filters help you focus on specific subsets of data, emphasize essential information, and facilitate interactive exploration. Tableau provides a variety of filter types to fulfill a variety of data filtering requirements.
Dimension Filters: Dimension filters can filter data based on categorical characteristics such as an area, a category, or a client group. When users utilize dimension filters, they can select a group of values, include or exclude specific values, or both.
Measure Filters: Filters allow users to organize data based on sales, profit, or amount. Users can utilize measure filters to create conditions, such as filtering data above a specific level or within a certain range.
Quick Filters: Quick filters allow you to interactively add filters to a picture by using your hands. They resemble drop-down menus or sliders; users can modify the filter settings while seeing the data.
Tableau Tools
Tableau includes various tools for analyzing and displaying data in various ways. These tools make it easier for individuals and businesses to work with data, create interactive representations, and make sound decisions. Tableau offers the following products:

Tableau Server:
Tableau Server enables employees in the same firm to share and collaborate on Tableau pictures. It allows Tableau Desktop users to upload workbooks and dashboards to a central server, where they may be viewed by authorized users using desktop or mobile web browsers. Tableau Server also includes capabilities for managing data, scaling it, and keeping it secure.
Tableau Online:
Tableau Online is a cloud-based data visualization solution that can be used in place of Tableau Server. It provides the same functionality as Tableau Server, but you do not need to install or manage a server to use it. Tableau Online allows users to securely upload, share, and collaborate on visualizations without operating servers on their premises.
Tableau Public:
Tableau Public is a free platform that allows anybody to create and share graphics. Users can make their Tableau graphics public by publishing them on the Tableau Public website. However, anybody can view visualizations shared on Tableau Public. A limited number of people or organizations cannot observe them.
Tableau Prep:
Tableau Prep is a data cleaning and organization tool. Before data can be viewed in Tableau Desktop, users must connect, integrate, and clean it from various sources. Tableau Prep provides users a transparent means to profile, shape, and validate their data. This makes it simpler for them to prepare their data for analysis.
Tableau Mobile:
Tableau Mobile is a mobile app available for iOS and Android devices. Tableau visuals may be accessed and interacted with while on the go. Tableau Mobile allows users to see and see dashboards on their mobile devices, receive data-driven alerts, and communicate with others.
Tableau Catalog:
Tableau Catalog is a tool for managing and finding information. It assists users in understanding and tracking the data used in Tableau workbooks and reports by providing information about where the data came from, how excellent it is, and how it is used. Organizations may manage their data assets effectively using the Tableau Catalog.
Tableau Extensions:
Tableau Extensions are add-ons that may be used to extend the functionality of Tableau Desktop and Tableau Server. Using these add-ons, users can add their data, infographics, and other services to the Tableau environment. Tableau Extensions are created using web technologies such as HTML, JavaScript, and CSS.
Tableau Parameters
Tableau parameters, or user-defined inputs, enable users to edit or interactively display specific portions of a worksheet. Users can use parameters to adjust values, select from different possibilities, or select data on the fly. This increases the flexibility and interactivity of data exploration and analysis.
How to create Tableau Parameters?
In Tableau, users can create parameters by specifying a data type (such as an integer, text, or date) and providing a range of valid values or options. Parameters can be configured at the workbook level and utilized in multiple worksheets and panels within the workbook.
