Data visualization provides a powerful way to dig into data, and Tableau is one of the leading software titles in the field. Tableau Desktop can measure and segment data in a variety of visual formats, allowing you to see patterns and outliers quickly. It hosts powerful tools that allow you to filter, sort, and organize data easily. It also provides a variety of data source connection types, both stored locally and hosted online. This means that you can combine data between multiple systems that otherwise would not talk to each other, further enhancing your analytic opportunities.

In addition, Tableau Prep Builder was developed to supplement the Tableau visualization tool. This data preparation tool further simplifies the data pulling process via an interactive visual interface. It lets you easily clean, aggregate, and combine data sources; preview the data; and identify data mismatches, typos, and other common data errors. Used together, Tableau Prep Builder and Tableau Desktop allow you to investigate and understand complex data sets and relationships.
