When I click on the text icon for showing data values in bar charts, it shows only a few values but not all. What’s the way around this?

  1. Tableau Desktop: It is a self service business analytics and data visualization that anyone can use. It translates pictures of data into optimized queries. With tableau desktop, you can directly connect to data from your data warehouse for live upto date data analysis. You can also perform queries without writing a single line of code. Import all your data into Tableau’s data engine from multiple sources & integrate altogether by combining multiple views in a interactive dashboard.

  2. Tableau Server: It is more of a enterprise level Tableau software. You can publish dashboards with Tableau Desktop and share them throughout the organization with web-based Tableau server. It leverages fast databases through live connections.

  3. Tableau Online: This is a hosted version of Tableau server which helps makes business intelligence faster and easier than before. You can publish Tableau dashboards with Tableau Desktop and share them with colleagues.

  4. Tableau Reader: It’s a free desktop application that enables you to open and view visualizations that are built in Tableau Desktop. You can filter, drill down data but you cannot edit or perform any kind of interactions.

  5. Tableau Public: This is a free Tableau software which you can use to make visualizations with but you need to save your workbook or worksheets in the Tableau Server which can be viewed by anyone.

Is SQL needed for Tableau?

Reply Icon Reply
Tobias

17 July 2020, 1:08 PM

SQL is not need if you want to learn Tableau and to work on Tableau but it is required to grab job because whenever you will get job and start working on project then you need to prepare Tableau dashboard using data.

Now question comes how data will come to you. sometimes you will get data in excel, csv or note files whereas sometimes client will give you access to production server and you will have to fetch data at your own. Now if you need to fetch data from any database then you must have the knowledge of SQL because SQL is the medium to talk with database and get answers in terms of data which you will use in Tableau or Power BI.

Now it does not mean when I am saying SQL then you should have database administrator level knowledge. Only SQL queries knowledge is enough to fetch data as per your requirement. Sometimes you need to prepare Tableau dashboard directly from database. In that case as well you will have to have knowledge of SQL because with the help of SQL you will prepare table in required format in database then you connect you Tableau with SQL Server/Oracle or any other database.

Just to summarize if you are already working in some organization and your manager and client asked you to learn Tableau as new project is about to come. then you need to ask your manager how they will data with you to prepare dashboard. On the basis of your client and manger answer you can decide to learn only Tableau or Tableau with SQL.

If you are looking for to learn Tableau to grab job and you are fresher and you do not have any other data processing software knowledge then you must learn SQL as well because organizations hardly hire anybody with only Tableau knowledge. You can search any job portal and see job description for Data Visualization Analyst or Tableau Developer or Tableau Analyst job. Then you will come to know what organizations are asking for. what you need to learn.

Is Tableau worth learning if my goal is to find work as a data scientist?

Learn it. You only need to invest 2-4 weeks, and you will gain 80% of the good parts of Tableau. You should also learn it because you want to be a data professional:

A data professional knows when to use the right tool. Tableau, R, Python, etc are all tools. If you think Tableau only makes beautiful graphs and dashboards, you do not fully understand the benefits of the tool.

A data professional looks for data, especially how other uses data. Is this a site license? Has your company set this as the enterprise standard? Many companies struggle with having any standards. If this IS how management and departments are monitoring Company KPIs, you better get to know Tableau. Because you will understand what data they care about, what insights they are trying to gain, and how they are calculating (or wrongly calculating) their numbers.

A data professional chooses the right medium of communication. While R and Python can also create beautiful graphs, documentation, etc. 95% of your non technical audience will not appreciate you used Jupyter, ggplot2, seaborn. What they care about is your findings. The majority of time, Word, PowerPoint, Excel, PDF, and BI reports (e.g. Tableau Reports) are what they are looking for, whatever they can easily open and view.

A data professional knows how to pitch his skunkworks. Tableau has R integration. Tableau connects to a variety of data sources, including big data type warehouses. Leverage these options to open doors for you to learn stuff at work. Tableau is just a entrance fee for you to do more data type projects.

A data professional always learn. Kudos to you that you want to prioritize your learning. This will be one of the many items where you need to decide when you are getting diminishing returns when learning Tableau, rather than a binary decision of learning it or not.

Is Tableau certification useful?

Meena Kumar

17 July 2020, 1:04 PM

More and more roles are now stipulating that some form of certification is required to demonstrate a high level of technical skill and ability to work in a timely manner, especially when Certified Professional is required. So in my opinion, it is definitely worth the investment of time and money. With the Tableau community and list of organisations using Tableau increasing the opportunities to use these valuable skills is growing everyday.

The key points covered in exam are:

  • Data connections
    -Organising & simplifying data
  • Field types and visual cues
  • Chart types
  • Calculations
  • Mapping
  • Statistics
  • Dashboards
  • Timeliness

It is recommended that some sort of formal training is taken to make sure you know all of the nitty gritty terminology that Tableau uses. This exam is by no means easy, and with a 2 hour time limit, you need to have your wits about you and be prepared.

What are some advantages of Power BI over Tableau?

Reply Icon Reply
Maria

17 July 2020, 1:02 PM

I would be using following Parameters to answer the question:

Cost:
Power BI is 9 to 10 times affordable compared to Tableau. Yearly subscription for tableau cost around $1000 compared to Power BI which is around $100. Now this margin is huge.

Implementation:
Again logging in to and implementing Power BI is much easier compared to Tableau.

Accessibility:
Power BI has taken great strides to make data access very easy. It is definitely edging out Tableau here.

Ease Of Use:
This is a personal opinion, amongst the two I found Power BI easier to use and one the major reasons why I love it.

These are few points I feel Power BI is better at. However the question you asked may boil down on the nature of business that needs to be governed, in those cases the comparison may be subjective to changes.
