Advantages
It is possible to link different views of the data and let the
user select the subset of data he is interested in.
Unlike few other visualization tools like Protovis, it doesnt
need the user to know programming.
It offers powerful tools in filtering and selecting data which
offer flexibility to the user in creating effective views of the
data.
The Show me tool box- When the dimensions and measures
of interest are selected ,Tableau suggests visualizations that
best suit the data.

Therefore during high traffic, it gets slow (Since everything is
done in a browser).

Business Value
Tableau as we have seen is very much useful in visualizing data both local andweb based.
It is possible to create dashboards and track KPIs
For example : If we want to track the effectiveness of a ad campaign on socialmedia
It is possible to track all these data
Location wise viewers
Total number of visits
Pages along with which it is visited
Increase/decrease in number of viewers over a period of time
It is also possible to construct a dashboard of these information together
We can also filter and deeply analyse the particular area, particular time ofvisits etc
Also if needed and if it exists, trends can be constructed using regression
There can be many applications of tableau in various domains like the aboveexample
