Tableau Training

Yes,Tableau Public is free software that enables anyone to connect to a table or file and generate web-based interactive data visualization. Tableau Reader is free to open and interact with Tableau Desktop data visualizations.

Tableau Public is a free service that allows anyone to publish visualizations of interactive data on the web. Visualizations posted in Tableau Public ("vizzes") can be integrated into web pages and blogs shared via social media or email and made accessible to other users for download.

The proprietary program language for writing Tableau is VizQL.

Tableau is not a database or a data warehouse system but it works on both. It is a data visualization BI tool. Tableau utilizes the features of direct access in data warehouses, allowing even the novice user to easily generate a visualization information extract, or create a live link. This is an outstanding function for Tableau because an extract can be produced in the visualization and hosted on a server based on the network capacities.

The difference is that you can't save your workbooks locally with Tableau Public. You need to save them to the public cloud, which means everyone can see your information. Tableau Desktop makes it possible to share your workbooks locally. This version enables you to connect to distinct kinds of files, generate extracts from sources of information and save your workbooks locally and publicly.

Yes,we can do predictive analysis with Tableau, using its versatile front end and intuitive visual interface. Information researchers are increasingly using the strong instruments of Tableau for advanced analytics and predictive modeling.

The answer is all three; it is a one-stop tool for all solutions.Tableau has an accessible in-memory information engine, called Hyper,  included in Tableau 10.5. Hyper can increase query velocity by 5X and can extract information from big data sets more quickly

Tableau Prep is an ETL (Extract Transform and Load) tool that enables you to extract information from a multitude of sources, transform information, and then return information for evaluation to a Tableau Data Extract (using the latest Hyper database as an extract engine).

The primary USP of Tableau is that it is a very useful instrument for viewing and reporting information.

Tableau can prove to be a great analysis and reporting tool for you. If you are a beginner, then you need to install the MySQL ODBC driver in order to create a data source to access the up.time DataStore. Once this installation is completed, you just need to:

• Configure the Report in Tableau
• Modify how the report displays information.

• Desktop-standalone desktop application (Windows or Mac) for dashboards and other content development and publication.
• Server-standalone application to publish and distribute the content created in Desktop .. Has many setup and administration alternatives, as well as APIs and utility commands. Can be accommodated on-site or in a cloud.
• Public-the same as the server, but Tableau is hosting. All content is public, free to use, limited to server, i.e. no user settings or management.
• Online-the same as server, but Tableau is hosting. It is a product based on SaaS paid subscription, content can be private or public, some management and configuration is feasible.

To allow users to eat the published material, server / online does not need a desktop, but Desktop is needed to publish the content.

Yes, they need Tableau Desktop. The browser-based tools(no software required to be installed) are Tableau Server and Tableau Online. Tableau Online does have the same Tableau Server features but is hosted in the cloud by Tableau. One point to note is that when it comes to server information links, there are some constraints. Small data sets that don't require high processing speeds like Tableau Server can use the  Tableau Online version. Tableau Server is a program used to safely share visualizations across an organisation and communicate with them. You must first use Tableau Desktop to publish workbooks on the Tableau Server.

It helps simplify the raw information into a format that is very easy to understand. The data analysis with Tableau is very quick and the generated visualization is in the form of dashboards. Data generated using Tableau can be grasped and visualized easily by professionals and laypersons alike. 

We have outlined seven best practices to increase the efficiency of your dashboards.

1. Get inspired: The trick is to take inspiration from as many places or people as possible. Get influenced and also influence others in the dashboarding process. 
2. Stay simple: It's tempting to put every chart or graph on them when you first begin to build dashboards. But de-cluttering is the  name of the game. Stick to that which is of relevance and keep your dashboard simple.
3. Use a grid layout: Using a grid format gives a logical layout to your dashboard, making it easy for your customers to read through and understand the data presented. You can generate a narrative that takes people from the overall to the details with a column or row-based flow.
4. Use the correct fonts:  While we all want our dashboards to look nice, let’s not commit fashion faux pas.  Too many fonts and sizes in a dashboard end up making it look cluttered and illegible. So, describe your typography in a straightforward hierarchy.
5. Don’t use too much color: Too much color does not necessarily add value to the dashborad. Again, the trick is to use only colors only for what is needed. 
6. BAN’s: Short for Big A** Numbers (BAN), your BANs can never be too big. So, give them the spotlight to ensure that they are immediately noticeable and create maximum impact. 

And finally collaborate and take others’ perspectives. No dashboard will be perfect the first time around, so keep iterating and you will have a winner!

One of the major reasons why Tableau is considered as one of the fastest evolving Business Intelligence (BI) and data visualization tools is that it is easy to learn. Moreover, it is very fast to deploy as well as intuitive to use for a customer.
