What is Tableau Architecture?

Tableau architecture refers to the underlying structure and components that make up Tableau software, which is a powerful data visualization and business intelligence tool. Understanding Tableau architecture helps users to effectively deploy and manage Tableau in their organizations. Here’s a high-level overview of the main components of Tableau architecture: ### 1. **Client Layer** - **Tableau Desktop**: This is a client-side application where users can create reports, dashboards, and visualizations. Users connect to various data sources, prepare and analyze data, and build visualizations that can be shared or published. - **Tableau Public**: This is a free version of Tableau Desktop where users can publish visualizations to the web. However, data is publicly accessible. - **Tableau Mobile**: This component enables users to access and interact with Tableau visualizations on mobile devices. ### 2. **Server Layer** - **Tableau Server**: This is a server-side application that facilitates the sharing and collaboration of Tableau visualizations and dashboards across organizations. It allows users to publish and manage Tableau workbooks, dashboards, and other content centrally. - **Tableau Online**: A cloud-based version of Tableau Server, which offers similar features as Tableau Server but is hosted by Tableau. ### 3. **Data Layer** - **Data Connectors**: Tableau can connect to a wide variety of data sources, including databases (like SQL Server, Oracle, MySQL), cloud data (like Google BigQuery), spreadsheets, and other data APIs. This flexibility allows users to pull in data from multiple sources. - **Data Engine**: This includes Tableau's in-memory data processing engine known as Hyper, which allows for fast query performance and allows users to work with large datasets. Hyper allows for efficient data extraction and aggregation. - **Data Storage**: Tableau can cache data for faster access and can also store extracts of data within its repository, allowing for offline access and performance optimization. ### 4. **Security Layer** - Tableau architecture incorporates security features at various levels, including user authentication (via Active Directory, SAML, etc.), permission controls, and data governance policies. These are important to ensure that sensitive data is only accessible to authorized users. ### 5. **Monitoring and Management Layer** - Tableau provides management tools and APIs for administrators to monitor performance, analyze usage, and manage content. This includes tools for scheduling extracts, performing background tasks, and checking server health. ### 6. **Visualization Layer** - This layer enables end-users to interact with dashboards and visualizations. As users explore data, Tableau dynamically queries the underlying data sources to provide real-time interactions and updates. ### Summary Tableau architecture is designed to provide a versatile, user-friendly platform that supports data visualization and analytics through various client applications and a powerful server infrastructure. By allowing connections to various data sources, implementing strong security measures, and offering multiple deployment options (on-premises or cloud), Tableau caters to the diverse needs of organizations looking to analyze their data and derive insights from it.
