What is Tableau?
Tableau is a BI Tool, that helps simplify data in an understandable format. With Tableau, users can try their hand at creating customized dashboards due to its intuitive and easy-to-understand user interface. Tableau has been widely sought after by people from various sectors since it doesn’t require any programming skills or technical knowledge to operate.
The data analytics in Tableau can be classified into the following two types:
- Sharing Tools: The purpose of these products is to share the visualizations, dashboards, and reports created using the developer tools. Tableau Online, Tableau Server, and Tableau Reader are the sharing tools that form a part of the Tableau suite.
- Developer Tools: These tools are used for development. This refers to the process of creating Charts, Reports, Dashboards, and Visualizations. Tableau Desktop and Tableau Public fall under this category.
Once the data has been pulled from a Data Warehouse, it can be extracted to Tableau’s data engine, Tableau Desktop, or connected live. This is where the Data Analysts and Data Engineers come in to develop visualizations. Dashboards that are created can be shared with the users in a status file. To view these dashboards, users can leverage Tableau Reader.
You can use Tableau Server to publish the data from Tableau Desktop. Tableau Server supports governance, distribution, security model, collaboration, and automation features. It enables the users to have a better experience through easy access to the files from any location.
Key Features of Tableau
- Tableau Dashboard: Tableau dashboard has an intuitive dashboard with self-explaining wizards, allowing non-technical users to create visualization easily. Dimensions, and charts are simple drag and drop on drawing space to perform analysis.
- Collaborative Sharing: Tableau allows users to collaborate with their peers for collaborative work or review. Users can also share to the cloud, which makes the dashboard accessible from anywhere.
- Flexibility: Using Tableau, you can extract data from databases like pdf, excel, text documents, R, Hadoop, Python, or SAS to cloud databases like Flipkart, Google sheet, Netflix, and Amazon.
- Data Sources in Tableau: Tableau has more than 200+ connectors that help users connect to external data sources like RDBMS, Cloud, spreadsheet, etc., securely. Tableau also provides several monitoring features such as data connectivity, auto-refresh, etc.
- Advanced Visualizations (Chart Types): Tableau has a vast collection of advanced visualization techniques. Some of them are:
What is Tableau Server?
Tableau Server is a popular centralized storage repository where you can easily bring all your related documents to a single central point. This allows you to protect your data and provide you with the best possible outcome.
Tableau Server houses a collection of processes that work together to offer a full self-service analytics platform for your users. When you install Tableau Server for your organization, it becomes a pivotal part of your analytics pipeline that can connect to live data sources. How you choose to offer data to your users would be dictated by a number of variables: performance, user scenario, access requirements, data source type, and infrastructure conditions.
Tableau Server can also be used as a web-collaboration platform, where users can connect to view, share, and interact with data sources and Data Visualizations from various devices. Tableau Server can integrate with various user authentication solutions like SAML, Kerberos, Active Directory, and OpenID.
Why do you need it?
You can leverage Tableau Server for the following scenarios:
- If you wish to keep track of the number of data sources being used along with the rapid increase of workbooks and dashboards, each with its own extracts, metadata layers, and copies; Tableau Server can come in handy.
- You can also leverage Tableau Server when you have high growth to deal with, or an uncontrolled environment warranting more security, governance, collaboration, and performance.
