Big Data
Everywhere you look, you see data—and lots of it. From online commerce data to new retail data via barcodes, it’s now common to need to work with millions and billions of rows of data. Companies and governments have realized that data is valuable, so they collect it and put it into a warehouse or cube or database.
But if it’s hard to comprehend a few thousand rows of numbers, what chance do you have to get insight from millions of rows at a time? How do you get value from all that data?
The proliferation of data makes easy-to-use business analysis tools more important than ever. The ability for business users to visualize data so they can spot trends and outliers is not nice to have, it’s critical. Otherwise you’ve got warehouses of data but no data intelligence.

Fast in-memory data engine
Tableau lets you bring your data into its fast, in-memory analytical engine, so you can get the data you need and answer your questions without overloading critical databases.
And Tableau's in-memory data engine is not subject to the restrictions of many in-memory solutions which require that all your data fit into your machine's RAM. Advanced in-memory technology takes advantage of all the memory on your laptop or PC, down to the hard disk, so your analysis can be wicked fast and huge, all at the same time.
And you always have a choice: with a single click between the options of live connect or in-memory analytics, you can quickly analyze samples of data then redirect to the entire database. Or take data in-memory to work offline, then reconnect again later.

No need to move data—just connect live.
Tableau has optimized direct connections for many high-performance databases and cubes, such as Teradata, Vertica, Essbase, Greenplum, Aster Data, and more. These let you take advantage of the capabilities of each database and provide the performance needed to do visual analysis of large data. And it’s easy to get started: just enter your credentials and begin.
As a result, no new data silos are created and large data tables perform exceptionally well. You can work directly with your data to create reports and dashboards. And you can embed dashboards with live connections in web pages for corporate portals, wiki’s etc.
