Granville believes their solutions are unique as they are packaged products combining all the following:
So key in all this is that Granville don’t provide..
just a data warehouse,
or just ETL,
or just OLAP,
or just work with one system
You can buy these components 'off the shelf', but the real major cost is then using and integating these components, and particularly getting data out of your systems into a single data warehouse. Such projects can take many months, if not years.
Granville Associates package all these components,
fully integrated into complete Business Intelligence solutions
which can be live within 2 months.
We are not aware of any other company that offers this.
