Tableau 2.0
Tableau 2.0 data analysis software has added a suite of features that facilitates the access and analysis of large data sets, including joining data from multiple databases. Version 2.0 also extracts data from a large data warehouse for sampling and analysis. Dynamic Calculations help users create custom aggregations, computed fields, totals and subtotals. In addition, the product helps define “on-the-fly” visual summaries that address quantitative problems involving running totals, moving averages, CAGR and percentage change.
