Tableau 10.1 includes new connectors and improved visual analytics capabilities to help you analyze your data even faster. For the enterprise, there is big extensibility enhancements and more tools for server admins.
some of the highlights include: JSON Support, Connectors for Marketing Data, Conditional Subscriptions, Drill Up on Continuous Data Fields and so on.
Tableau Desktop is based on breakthrough technology from Stanford University that lets you drag & drop to analyze data. You can connect to data in a few clicks, then visualize and create interactive dashboards with a few more. We’ve done years of research to build a system that supports people’s natural ability to think visually. Shift fluidly between views, following your natural train of thought. You’re not stuck in wizards or bogged down writing scripts. You just create beautiful, rich data visualizations.
It’s so easy to use that any Excel user can learn it. Get more results for less effort. And it’s 10 – 100x faster than existing solutions
Tableau Server is a business intelligence application that provides browser-based analytics anyone can use. It’s a rapid-fire alternative to the slow pace of traditional business intelligence software. What makes Tableau different? It’s designed for everyone. There’s no scripting required, so anyone can become an analytics expert. You can grow your deployment, as you need it. Train online for free. Find answers in minutes, not months.
Tableau Online is a hosted version of Tableau Server. It makes rapid-fire business analytics easier than ever. Share dashboards with your whole company and with customers and partners— in minutes. Provide live, interactive views of data that let people answer their own questions, right in a web browser or on a tablet. And do it in a secure, hosted environment. Tableau Online can scale up as much as you need and you can use it wherever you need it. You don’t need to purchase, set up or manage any infrastructure.
Tableau Public is for anyone who wants to tell stories with interactive data on the web. It’s delivered as a service that allows you to be up and running overnight. With Tableau Public you can create amazing interactive visuals and publish them quickly, without the help of programmers or IT. The Premium version of Tableau Public is for organizations that want to enhance their websites with interactive data visualizations. There are higher limits on the size of data you can work with. And among other premium features, you can keep your underlying data hidden. Why tell stories with data? Because interactive content drives more page views and longer dwell time. Industry experts have cited figures showing that the average reading time of a web page with an interactive visual is 4, 5 or 6 times that of a static web page.
Here is a brief tutorial on analyzing data with Tableau (using Tableau 9):
Let’s explore a company that sales computer peripherals and has its sales representatives across the different parts of United States. We’ll start with a very simple file that has only 6 columns- order date, region, Sales rep, item, unit, unit price. So, the data is about all transactions that happened over all the 4 regions and the items that were sold in each of these regions and the sales rep who was responsible for the sale. As part of our analysis, we’ll create our own calculate field, work with colors, add labels, formatting the chart, exporting the worksheet and few other things to build a solid foundation.
In the left side of the screen we have a list of options under Connect. We will select the text option to bring the data from a csv. We browse to the directory and select the csv file. Once you have selected the file you can see a preview of the file in Tableau.
On the left side of the window you can see a Data tab and Analytics tab. The data tab represents the database. If you right click on it, and select view data, you will be able to see the data with the columns rearranged, but it’s similar to the preview window that you have seen before.
If you want to connect to another data source you can just go to data and select new data source and a list of data sources will appear to connect. You’ll have the options to connect to Excel, Text file (including csv), Access, Statistical file and other files. Statistical file consists of files from SAS, R and other statistical tools. These are some data sources Tableau can work with.
If you select more servers you can connect with a number of dataoptions. There are options for connecting to Hadoop or Big data sets using PostGreSQL, Pivotal Greenplum database.
