Tableau

Kommentare: Tableau has allowed our office to look at data in new ways. Whether we're using it for data exploration or dissemination, it makes the information easy to understand and use, even for newbies. In the past, we used spreadsheets and PDFs to share data with various constituents, but they were dense and only offered a static view of the data. Now, with interactive dashboards, end-users can not only search for the exact information they need, they can also see how it fits into the big picture. This capability has led people to ask more questions and actually get excited about data and assessment. Tableau allows us to answer those new questions quickly and accurately than before.

Vorteile: I have been using Tableau Desktop for over five years now and I still get excited about it. First, Tableau is so easy to learn and use--the intuitive interface allows even first-time users to create amazing visualizations. Second, Tableau is a time saver. What used to take me weeks now takes days and what used to take days now takes minutes. Third, Tableau is versatile. There are many different chart types available, and with the ability to tweak everything from size to font to color, your imagination is the only limit. Fourth, Tableau is always evolving and improving. With each update, Tableau adds new features and capabilities that continuously make my job easier to perform. The software is capable of connecting with data in many different formats from spreadsheets and SQL to PDF's and spatial files, making it useful for any field or company that works with data. I could go on and on about the benefits of using Tableau, but the best way to understand my enthusiasm is to try the product--it speaks for itself!

Nachteile: Sometimes large data files can take several minutes to load. Tableau allows for the creation of extracts to speed up the process, but the initial upload still takes time. Tableau also does not have an auto-save feature, which has caused me to lose work on several occasions.

Kommentare: I started using it while I was making my MBA and I was amazed at the easy of use and the possibility to make chart in a very powerful way beyond excel. Later on, when I was asked to do some complex representation of many parameters, Tableau has been the best and easiest option, beyond other 3 options I have tried from major sellers

Vorteile: - Very intuitive way o assemble data, no need for programming or special commands
- Easily change data from numeric to alphanumeric
- The most common and useful charts are available
- Easy to breakdown data into several clusters
- I once plotted 6 parameters in a 2 dimensional chart: X, Y, bubble size, color, name, icon
- You can build special read-only docs with the functionality to be read by Tableu Reader (as in acrobat reader)
- You can customize label, axis, trend and references lines

Nachteile: - Eventually some very specific charts are not there as chord, tornado, tree maps, nodes, gauges, alluvial diagram, dendograms
- Even with all the clustering, it lacks statistical analysis as Anova, hypothesis test between two set of data, normal probability plot

Kommentare: I generally use tableau to show sales data on dashboards to executives. Overall experience is great now that I have enough skill to operate and manipulate the data to generate what I want.

Vorteile: I like that you can merge different data sources to generate new views of data. for example, overlay a census report above your sales data and have a demographic profile of sales for the country. Also the hundred different graphs and charts to choose from. this scores me high points with the executives when I show them a fancy graphic in meetings.

Nachteile: We had some trouble with tableau speaking to our servers and applications which took longer that we wanted before we could start using live data to run reports. You must clean your data before you upload to tableau. the data scrubbing system on tableau needs work. This makes it difficult when using live data. I usually just use and extract, clean and upload.

Kommentare: I have been using Tableau in the office for over 2 years now. It is a product that continues to develop and evolve to better serve as a data visual and analysis tool.

Vorteile: Tableau is a great data visualization tool. If you need to make charts, graphs, tables or other types of data visuals, Tableau can get it done. You are able to upload files or connect directly to data sources on a server. After data is loaded, it is literally a drag and drop interface.

Nachteile: Tableau is great for creating visuals but is not so great as a data analysis tool. It lacks the ability to analyze and manipulate data that uses complex formulas and calculations.

Kommentare: It's a good visualization tool. but price is not as cheap as we thought.

Vorteile: Extract data source - hyper. we converted some Cognos reports to Tableau, in Cognos we have to pre-schedule it because the complex query behind the scenes takes long time to run. At beginning we
use Tableau live connection, put most of calculations in ETL but still getting performances issue.
after switch to hyper...oh it's fantastic.

Nachteile: In Cognos, to view Query behind FM model or Report just one click, it's very helpful and convenient during development and troubleshooting. In Tableau have to dig into log to find the query or check from DB side.
