Business Objects and Business Warehouse!

Hello ,

Busines warehouse is a type of data warehousing tool from
SAP which covers extraction, modelling and reporting which
is having complete  package
to be honest, both are really BAD.

Try using Cognos or other third party tools, which are ten times better then BW or BO.

Or work with SQVI (tcode in SAP) and RFC with office which I find much better then those two.
SAP BW doesn't really exist anymore. It's now Business Intelligence. And it's actually great for reporting the same data month after month. It's however NOT very good at reporting "on the fly" new information readily. Some thought needs to go into the design of each report as the amounts of data in a normal BI system can be rather extensive, and inefficient design leads to slow reporting.
GRabbing data from external sources is very easy, as is the reporting, however, as I said design your datamodels and reports carefully. Especially the features such as net reporting that utilizaes JAVA gets hit very hard if you're using a bad design. Follow guidelines regarding designing a report and you'll do fine with SAPs BI.
IMO the only major downside is the cost. If you dont have an SAP solution to begin with costs are insane, especially with the new licensing structure.

So i assume:

BI or BW is all about reporting(nothing else).Creating reports for some data

Could u explain what kind of data is this reporting ? use ? eg?
Well, It's basically infocubes that you datamine. And while I'm sure that a BI system CAN do more than just report on the data it contains, I can't think of anything more that it should need to do. But needs vary from person to person so if you have other needs, you should ofcourse ensure that they're covered by the system before choosing which system you want.

Normally you'd datamine information like, say sales, logistics, production, marketing etc. Then create reports based on that data. for instance if you manufacture more than you sell, you can use the reports to determine storage needs and locations. You can view sales from many perspectives, ie. does costumers who buy toothpaste also buy bicycles ?
Again the reports you choose (or create if no default report exists that covers your need) should address your requirements for reporting, so it comes down to what information do you WANT the system to report to you about ? What data do you have available ? And is this sufficent ?
