Caselet Data Warehousing is next Growth Area: Inmon

R BILL INMON speaks the language of computers that help better extract
information stored in unstructured forms be it speech, e-mail or text, a challenge
Mthe industry is trying to find a solution.
Considered as the father of data warehousing, Mr Inmon, is in India speaking about data
warehouses and guiding techies in mining data and making them meaningful for
enterprises.

Mr Inmon told Business Line data warehouses would grow exponentially; however, the
industry is faced with the challenge of extracting unstructured data and making it
meaningful, for its users in corporations and Government.
Because of the growing competition, companies cannot do without data warehouse. The
data stored in these centres provide the right path for informed decision-making. Areas
such as retailing, insurance, banking and telecom services are extremely dependent on
data, which make them drill deeper into the existing clients and also offer them right
services and solutions.
“Just like the traditional outsourcing services, data warehousing can actually be outsourced
to third party depending upon the nature of business. Therefore, I expect a wave of data
warehouse outsourcing through the proven global delivery model. However, it is not
without own checks and balances,” he explained.
Countries such as Germany and Denmark by law prevent any data from leaving the
country. “In fact, if you look at large corporations in the US, it is clear that data warehouse
is much more entwined with the business itself. SAP, the enterprise software vendor, is
one of the world’s largest providers of packaged data warehouse and has recently passed
10,000th licence, which is significant. It is here that the issue of business intelligence and
analytics comes into play”, he said.

Accuracy and integrity of data is a key issue. There are different approaches to data
warehouses, one that relates to Oracle and the other that is referred to the IBM way.
