The implementation of SAP BI starts with operational
reporting ie reporting on the operational data sources. Mostly the users run
queries on operational data sources. What happens is that, this creates a
reporting backlog. As a result the customer needs Ad Hoc reporting or self
service reporting. So this can be achieved by putting a Ad Hoc tool on top of
the operational data source.
The operation data sources are not really designed for the
end users to make senses of the data. This actually creates a little bit of a
challenge here. This is the data challenge. So the customers start to do data
marting projects and this is largely to expand the Ad Hoc initiative.
Once they are done with data marting, they also start to do
things like Dashboards. They want to do this for making better decisions. They
do it on single data sources and multi data sources. So they are actually
building more and more data marts. This gives them more holistic view of the business.
And then what is going to happen in the company is that there is going to be
scorecard like initiatives.
This will create another data challenge that is going to
drive data warehouses. This is where the scorecard initiatives starts to span
the entire enterprise and moves into things like balance scorecards. Once all
this is done, the company starts to build things like analytical applications.
