Because of its intelligible forms, Tableau data is more accessible for people of all levels to digest. While the learning curve for Tableau dashboard development is slightly steeper than Power BI, given it is geared more towards data analysts than casual users, it still doesn’t require you to be highly technical.
Power BI
With Power BI, the core publishing tool is Power BI Desktop. It enables a variety of features to create new models and reports. Power BI Service is a cloud-based SaaS service that hosts Power BI models, reports, and dashboards. Data collaboration and interchange occur in the cloud using the Power BI Service.
The Power BI service is a secure Microsoft-hosted cloud service that allows users to access dashboards, reports, and Power BI applications – a form of content that integrates linked dashboards and reports — through a web browser or mobile apps for Windows, iOS, and Android.
Power BI Desktop is a free, self-service data analysis and report publishing solution for Windows computers. It can link to over 70 on-premises and cloud data sources to generate dynamic graphics. Data scientists and developers use Power BI Desktop to create reports that are then delivered to the Power BI service.
Power BI Pro is a cloud-based program that costs $10 per user per month. The ability to communicate with other Power BI users and deliver reports and visualizations to other Power BI subscribers across the enterprise is the most significant distinction between Power BI Desktop and Power BI Pro.
Tableau
The Tableau Platform is comprised of a variety of products that allow users to combine diverse data sources and generate data visuals that can be shared internally and publicly. You can choose which products are best suited to your organization when arranging your licensing agreement with Tableau.
Tableau Desktop is a data visualization application for creating interactive dashboards and reports. Tableau Desktop's strength is its ability to easily turn data into data visualizations such as charts and graphs to create a story with your data. Real-time analytics can also be enabled by connecting directly to data sources that include live data. In addition to real-time capabilities, Tableau's data engine allows you to effortlessly import data from numerous sources and combine it by merging several views in an interactive dashboard.
Tableau Server is a platform where you may store all of your Tableau information, including workbooks and data sources. Tableau Desktop is used to generate dashboards, which are subsequently published to Tableau Server and shared with the appropriate individuals in your business. Tableau Server is a collaborative working environment that eliminates the requirement for worksheets to be downloaded and opened. You can manage and secure projects, just like many other server technologies or file-based repositories, to stimulate cooperation with the appropriate people.
Tableau Online is similar to Tableau Server, except it is a cloud-hosted analytics solution that eliminates the need to manage and maintain hardware. This enables faster and easier setup and configuration, as well as mobile access to business analytics. Dashboards generated in Tableau Desktop can be published and shared with others.
Tableau Reader is a free desktop version of Tableau that just allows you to see Tableau visualizations. This means that you can interact with visualizations by filtering and drilling down on data, but you can't alter them.
Security
Power BI adheres to Microsoft's security standards and regulations and tight security compliance criteria. Every Power BI deployment has a web front-end and back-end cluster. Data is sent across two clusters to avoid security compromises, and clients are continuously authenticated.
Tableau provides many authentication options, including trusted authentication, mutual SSL, personal access tokens, and Kerberos. Tableau's security features include advanced network security and encryption. Tableau may additionally protect live data sources by enabling database credentials in published view. Tableau administrators have a variety of choices for keeping data safe.
Ease of Use
Power BI provides end users with real-time dashboards a data analysis. To improve the user experience, the tool also has superb drag-and-drop functionality. Users do not require substantial technical knowledge to use its robust data analytics and discovery features.
Tableau also has powerful dashboard and reporting options, albeit some of them are less straightforward. Tableau's live query features are advantageous to analysts. Along with query-based visualization, the Tableau BI tool includes drag-and-drop functionality. To utilize all of the capabilities successfully, you might want to spend some time researching the Tableau UI and feature set.
