Reports Vs Dashboards

Q: What is difference between a Report and Dashboard ?

Wrong Ans: This is the question that i have asked to many people and most of them answers : Dashboards are interactive and reports are not. (Which is not correct)

Those who thought of same answers, just tell me can't i have a report with any of BI tools which can have some interactivity..... yes wen can have many interactive options in a report.

Then, whats the difference...

"to take a decision you need to process the information from a report, while Dashboard  provides you processed information which can be directly consumed and you can directly take decision based on it."

for example - your car dashboard. When you look at your car dashboard it shows you speed. Your car speed is the information which you can directly consume and can take decision like slow down or accelerate more. Suppose, instead of speed in Miles/hr or KM/hr , if dashboard would show you the rpm of your wheels and the distance covered by wheels in one revolution then you might have to calculate the speed using the information available and then come to decision.

This examples helps you what to show in your Dashboard and what not. Only that information should be shown in a dashboard which can be consumed directly with out any processing and is really required.

Comparing BO Webi vs SSRS

Webi from BO and SSRS from Microsoft are always in competition with each other. Both of them are good products catering to similar business needs in different styles. I have been using Webi and SSRS for my projects and i always think first which one should i use before starting a new one. Here i would be doing this comparison that may help others to opt between the two.


  1. Formatting - SSRS provides you good flexibility in formatting your reports but Webi does it better. In webi you can align your components charts with better look and feel than SSRS. Also formatting is easier in webi as its all gui based while  in SSRS its all visual studio like environment so bit of complexity.  Hence i would give webi 5 and SSRS 4
  2. Rendering - SSRS rendering is really bad when it comes to PDF, they don't give bookmarks for tabs in report. Also quality of formatting in Webi generated PDF is better. Here SSRS looses and webi wins. Hence Webi gets 5  and SSRS 3
  3. Ease of use - Again webi takes advantage here. SSRS is too complex for a new beginner. Like tablix concept, conditional formatting and all, everything is expression based which makes it too much to code.  i will give webi 4 and SSRS 3
  4. Flexibility - Here SSRS is champ. you have got every thing to be modified as per your requirement. You can use custom functions, custom codes, colors, borders, text, and any property can be made dynamic using expressions. While in Webi only limited things are there to be modified. so Webi gets 2 and SSRS gets 5
  5. Error reporting - When you schedule webi and if it gets failed, Webi gives you error details specifically. While, in SSRS error details is mostly generic. Webi gets 5 and SSRS gets 3
  6. Managing History Instances - SSRS have tried to do a lot but less when comparing to Webi. Webi is better. Webi 5 and SSRS 4
  7. Error prone - While working with webi, there have been many instances where you just cant explain the erroneous behavior of Webi reports. Some times your report tabs goes away, some times you formatting your webi formatting is corrupted. And most of all java creates a lot of problem while working with webi. In case of SSRS its completely free of such errors. So SSRS 5 and webi 2
Finally total scores : Webi  - 28 and SSRS -  27

Over all if you are looking for better formatting and easy to use gui Webi is for you. But if you want better flexibility and less rework then SSRS can be the choice.
