DATA WAREHOUSE AND THE WEB
Professor Peter Drucker, the senior guru of management practice, has admonished IT
executives to look outside their enterprises for information. He remarked
that the single biggest challenge is to organize outside data because change
occurs from the outside. He predicted that the obsession with internal data
would lead to being blindsided by external forces.
The majority of data
warehousing efforts result in an enterprise focusing inward; however, the
enterprise should be keenly alert to its externalities. As markets become turbulent,
an enterprise must know more about its customers, suppliers, competitors, government
agencies, and many other external factors. The changes that take place in the
external environment, ultimately, get reflected in the internal data (and would
be detected by the various data analysis tools discussed in the later
sections), but by then it may be too late for the enterprise. Proactive action
is always better than reacting to external changes after the effects are felt.
The conclusion is that the information from internal systems must be enhanced
with external information. The synergism of the combination creates the
greatest business benefits.

challenges faced in integrating external data with internally sourced data by

is often distributed through the internet.

Reliability of Web Content
Many question the
reliability of web content, as they should. However, few analyze the
reliability issue to any depth. The Web is a global bulletin board on which
both the wise and foolish have equal space. Acquiring content from the Web
should not reflect positively or negatively on its quality.
