Number of silos in which your customer data resides.
Coincidentally, also the number of totally different
defi nitions you have for “customer.”
Embarcadero solutions help manage data
enterprise-wide, enabling you to build and
communicate an architecture of your data assets
so you always know what is what, and where it is.
With just one, everything gets simpler. You and
your business are empowered to use and reuse
reliable, relevant, and timely data across a range
of platforms and storage formats. Understanding
your data is fi nally possible, and getting a hold
of the metadata is the key. Standards can be
defi ned and enforced. Data redundancy is
eliminated. It’s no coincidence that the most
sophisticated solution is also the simplest.
See how one gets it done.
