Data visualization brings your data to life, turning numbers and statistics into dynamic and insightful visual representations that can help you better understand, analyze, and communicate your data. One of the top data visualization tools is called Tableau.
What is Tableau
Tableau enables individuals and companies to become more data-driven. The Tableau analytics platform, the market-leading choice for modern business intelligence, makes it easier for users to explore and manage data and find and share insights that can change industries and the world economy.
Main Products of Tableau:
Tableau offers a range of products to suit different needs and use cases. Here is an introduction to the five main products offered by Tableau:
Tableau Desktop
Tableau Desktop allows users to connect to a wide range of data sources, including Excel spreadsheets, CSV files, databases, and cloud-based data sources. Once connected, users can use Tableau’s visualization tools to create interactive charts, maps, and dashboards that help them see and understand the data in new ways.
Tableau Desktop also offers a range of features for analyzing and interacting with the data, including filters, grouping, and calculations. This allows users to drill down into the data, explore different scenarios, and uncover insights that might not be immediately apparent.
Once users have created their visualizations, they can publish them to Tableau Server or Tableau Online to share with others, or save them locally for offline use. They can also use Tableau’s APIs to integrate their dashboards and visualizations into custom applications or websites.
Tableau Server
Tableau Server is a product that allows users to securely share and collaborate on data visualizations and dashboards within an organization. It provides a web-based platform for publishing and accessing Tableau dashboards and reports, enabling users to share insights and data-driven decisions with their colleagues easily.
One of the key features of Tableau Server is the ability to schedule updates to dashboards and reports, ensuring that stakeholders always have access to the most up-to-date information. It also includes permission controls, allowing administrators to set user permissions and manage access to specific dashboards and data sources.
In addition, Tableau Server includes tools for data governance, such as data lineage tracking and source management. As a result, it helps organizations ensure that their data is accurate, secure, and compliant with relevant regulations and policies.
Overall, Tableau Server is a powerful tool enabling collaboration and data-driven decision-making within an organization. It helps teams access and analyzes data in real-time, improving efficiency and enabling more informed decision-making.
Tableau Online
Tableau Online is a cloud-based version of Tableau Server, allowing users to access and share data visualizations from any device with an internet connection. It provides all the features and capabilities of Tableau Server, including publishing and sharing dashboards and reports, scheduling updates, setting user permissions, and managing data governance.
Tableau Online also offers the advantage of being cloud-based, which means that it is managed and maintained by Tableau, eliminating the need for users to worry about hardware and software installation and updates. It also allows for easier scalability, as users can easily add more users or data sources.
Tableau Public
Tableau Public is ideal for data journalists, researchers, and anyone looking to share their data-driven insights with a wider audience. It allows users to upload data from various sources, including Excel spreadsheets, CSV files, and databases, and use Tableau’s visualization tools to create interactive charts, maps, and dashboards.
One of the main benefits of Tableau Public is the ability to share data visualizations with a global audience. Published visualizations can be shared via social media, embedded on websites, or via a link, making it easy for users to share their insights.
Tableau Public is a free service, and users do not need to purchase a license or subscription. However, one should note that visualizations published on Tableau Public are publicly available and can be accessed by anyone with the link, so users should exercise caution when sharing sensitive or confidential data.
Tableau Reader
The free Tableau Reader lets users view and interact with dashboards and visualizations, including filtering and drilling down into the data to explore different scenarios and insights. Data in exported, packed workbooks is fixed. Tableau Reader cannot automate data refreshes compared to the other products. Additionally, bundled workbooks lack security features like password protection.
End users’ functionality is limited to what has been pre-configured, such as dashboard activities and filters. As a result, Tableau Reader does not offer self-service analytics for an additional examination of unresolved queries. This application must be installed locally and cannot be used on a mobile device. Tableau Reader lacks the security features that many businesses need.
How does Tableau work?
Tableau is a data visualization and business intelligence software that helps users see and understand data in new ways. It provides various tools and features for exploring, analyzing, and presenting data in various formats, including charts, maps, and dashboards.
To use Tableau, users typically start by connecting to a data source, such as an Excel spreadsheet, a CSV file, or a database. Tableau allows users to connect to a wide range of data sources, including popular databases like MySQL and SQL Server and cloud-based data sources like Google Sheets and Amazon Redshift.
Once the data is connected, users can use Tableau’s visualization tools to create interactive charts, maps, and dashboards that help them see and understand the data in new ways. For example, users can create pie charts to see the proportions of different categories within a dataset or use a scatterplot to explore the relationship between two variables.
Tableau also provides a range of features for analyzing and interacting with the data, including filters, grouping, and calculations. It allows users to drill down into the data, explore different scenarios, and uncover insights that might not be immediately apparent.
Once users have created their visualizations, they can publish them to Tableau Server or Tableau Online to share with others or save them locally for offline use. They can also use Tableau’s APIs to integrate their dashboards and visualizations into custom applications or websites.
