OBIEE

The recent project was really helpful in understanding how BI works in a current enterprise whether be it healthcare or retail or forecasting based on historic data.
The tool OBIEE is a really helpful OLAP tool where you can create almost any report you want to create. The dimensional model of the data eases the complexity as the facts and dimensional tables really help one understand the details he/she is looking for and pull the necessary details to present the output as desired.
Whats improves the tool is the ease with which a person can plot various graphs and not only plot them but change the various components to get the exact data representation they are looking for. With the wide variety of details provided be it a pie chart, line graph or anything else, along with being able to swap the columns as X or Y axis is also a very convenient way by which one can present his manager easy decision making capability.
The best part is the mobility component of the whole process. You don't necessarily have to be tied down to a system and the connected server to procure the data you desire.
This is the future of BI reporting on the go!! And with the Oracle's latest service which allows users to pull reports from their iPads and other tablets makes the market more futuristic.
There is still more to come like Real time BI. Well we are still chasing our dreams and real time BI is not the end of it, as every distance you cover shows the path that lies ahead.
