Avail #1 Tableau Assignment Helpers

Tableau is a data visualisation application used in the business intelligence sector that is both strong and rapidly increasing. It aids in the transformation of raw data into a format that is simple and easy to understand. Tableau assists in the creation of data that may be comprehended by professionals at all levels of an organisation. Non-technical people can also modify dashboards. The Tableau application allows for quick data analysis, and the representations created are in the form of dashboards and worksheets.

The best part about Tableau software is that it can be used without any technical or programming knowledge. The tool has piqued the curiosity of people from many kinds of backgrounds, including businesses, researchers, and various industries.

Tableau is designed in such a manner that all types of charts, plots, and graphs with various designs can be positioned for visualisation at the same time. Tableau is a fast-growing visualisation tool that may be used for a variety of commercial applications. It's a popular piece of software since it's simple to use. 

Tableau can retrieve data from databases such as pdf, text documents, Hadoop, Python, excel, R, or SAS and upload it to cloud databases such as Flipkart, Google Sheets, Netflix, and Amazon. Tableau is an example of a programme that recognises the platform a user is using and optimises reports appropriately, giving them the optimal viewing choice.

Tableau is an interactive data visualisation software company based in the United States. Tableau has a large number of products that are divided into categories based on their function. The various types of tableau products are:

Tableau Desktop: Tableau Desktop is a powerful tool that lets you code and customise reports. From developing the charts and reports to blending them all to produce a dashboard, all of the essential work is done in Tableau Desktop. Tableau Desktop connects to the Data Warehouse as well as other types of files for live data analysis. The dashboards and workbooks developed here can be shared privately or publicly.

Tableau Public: It's a version of Tableau that's been designed specifically for budget-conscious customers. The workbooks created cannot be stored locally; instead, they must be saved to Tableau's public cloud, where they may be viewed and accessed by anyone. The files saved to the cloud have no privacy since anyone can see and download them. This version is ideal for people who wish to study Tableau and share their data with others.

Tableau Online: Tableau Online is a cloud-based sharing platform that links to Tableau Public and Tableau Desktop, similar to Tableau Server. It has similar features to Tableau Server, but the data is kept on the servers hosted in the cloud, managed by the Tableau group. The amount of data that can be published on Tableau Online has no restrictions.

Tableau Server: The software is used to share Tableau Desktop worksheets and visualisations across the organisation. Users must first publish their work on Tableau Desktop before sharing dashboards on Tableau Server. Only licenced users will have access to the work once it has been submitted to the server.

The licenced users, on the other hand, are not required to have Tableau Server installed on their machines. They only need the login credentials to access the reports through a web browser. Tableau Server has a high level of security and is well suited for quick and effective data sharing inside an organisation.

Tableau Reader: Tableau Reader is a free desktop programme that allows users to open and interact with worksheets and visualisations created with Tableau Desktop or Tableau Public. The data can be filtered, but it cannot be edited or modified. In Tableau Reader, the security level is zero, which means that anyone who receives the worksheet can see it using Tableau Reader. If users wish to share the dashboards they have built, the recipient must have Tableau Reader installed on their computer.

Tableau is gaining popularity in today's world. Tableau is an effective data visualisation application in the business intelligence industry. It supports the conversion of textual and numerical data into visual dashboards that allow people to see and comprehend their data. Tableau's dynamic, simple, fast, and user-friendly design has made it highly popular. The advantages of using Tableau are:

Quickly create interactive Visualisations: Tableau's drag-and-drop functionality allows users to construct a highly interactive visual representation. The interface can support an infinite number of variations while also preventing users from making charts that violate data visualisation best practices.

Data visualization: Tableau offers a variety of visualisation options. The technology is available to allow complicated computations, data blending, and dashboarding in order to create stunning visuals that give insights that are difficult to derive from staring at a spreadsheet. Because of its dedication to this objective, it has risen to the top of the data visualisation heap.

Ease of implementation: Tableau offers a variety of visualisation choices to help users get the most out of their data. This tool is easier to understand and implement than Python, Business Objects, or Domo. Tableau is simple to learn. The most significant benefit of this tool is that it can be mastered by anyone who has no prior coding experience.

Tableau can handle large amounts of data: Tableau can easily manage millions of rows of data. Users can develop many types of visualisations with enormous amounts of data without affecting the dashboards' speed. 

Mobile support and Responsive Dashboard: The use of smartphones is growing day by day. As a result, having a technology that allows mobile users to access and view reports and dashboards is crucial. 

Tableau Dashboard offers a remarkable reporting option that lets users modify their dashboards for specific devices such as smartphones and laptops. Tableau automatically detects which device the user is using to view the report and makes the necessary adjustments to verify that an accurate report is provided to the correct device.

Support multiple scripting languages: Users can utilise R or Python programming language to overcome performance issues and execute complex table calculations in Tableau. By conducting data cleansing operations with packages using Python Script, the user can reduce the software's burden. Tableau, on the other hand, does not support Python as a native language. However, Python's visual packages can be imported.

String Data type: The string data type is a text data type that contains any character sequence containing zero or more characters. When the characters are wrapped in a single or double quote, the value is considered a string. String Data type is of two types- 

Char string type: This data type's values have a fixed length. Tableau allocates memory for char string type values that correspond to this fixed length. If users try to input a string value that is longer than the specified length, the system will give you an error message. This data type is most commonly used to store alphanumeric data values.

Varchar string type: Varchar string type also known as Variable character length string type denotes that the length of the characters to be inserted in a string is not fixed or preset. There are no memory allocation restrictions, so users can enter as many characters as they like. Alphanumeric data values can be used with this string type.

Numeric Data Type: Integer and floating data types are available for numeric data types. Because users have difficulties accumulating the decimal point after a certain limit with float numbers, most fields with numeric data types are of integer type. After rounding up float numbers to equivalent integers, they can be conveniently employed in calculations. 

Date and Time Data types: Tableau can accept practically any format of a date. Date and time values can be in a variety of formats in Tableau data types. There's also the option of placing a hash (#) symbol before the date value to add it in string character format.

Boolean Data types: Relational calculations provide the boolean data type values. As a result, logical values are defined as True and False boolean values. When the result of a relational calculation is unknown, null data values are used in this case.

Geographic Data type: All data used in a map is the geographic data values. The geographic data type includes values such as country, state, city, region, postal codes, and so on. 

In comparison to other Business Intelligence tools, Tableau allows its users to produce impressive graphics in a matter of seconds. It enables users to complete difficult jobs using simple drag-and-drop functionality, allowing the system to solve any questions. It's based on a proprietary programming language called VizQL, and it uses a drag-and-drop interface to assist non-technical people in turning big data sets into stunning, dynamic graphics while allowing more expert users to edit their graphics even more.

Identifying critical insights in data allows businesses to stay competitive in their respective sectors. Tableau enables these businesses to extract hidden insights from their data and present them in an easily understandable format.

Tableau offers a variety of ways to use it, based on the demands of different types of businesses. As a result, a student, an organisation, a data analyst, or even a journalist, anyone can use it. Data may be accessed from any location and shared across the enterprise using a desktop or mobile browser.
