Caselet 1
Most companies store reams of data about their customers. The IT challenge has been how to
integrate and massage that information so the business units can respond immediately to changes in
sales and customer preferences.
Hency Schein Inc. (www.henryschein.com) has it figured out. The $2.8 billion distributor of
health care products designed and built a data warehouse with an in-house team of six IS
professionals. CIO Jim Harding says he knew that having the right skills was critical to the data
warehouse project, yet at the time, Schein had zero warehousing experience in its IT shop. So he and
Grace Monahan, vice president of business systems, hired people for what they call “Team Schein.”
Because Harding had chosen ...
daily, weekly, monthly and quarterly – for the analysis of sales and market trends. But today,
business users search, sort, and drill down for that information themselves in a fraction of the time.
The data warehouse has become “a part of our culture,” says Harding. “It’s got that kind of aura
about it within the company.”
1. What are some of the key requirements for building a good data warehouse? Use Henry Schein
Inc. as an example.
2. What are the key software tools needed to construct and use a data warehouse?
Caselet 2
The return on investment from voice-over-Internet protocol (VOIP) technology has proved difficult,
in part because upfront costs can be high and traditional long-distance phone charges have dropped
in recent years. Adding voice requires that all elements of the corporate network be tested – and in
some cases replaced or upgraded – for VOIP applications.
Grant Thornton. Chicago-based Grant Thorton Inc., (www.granthornton.com) , a global accounting
and auditing firm, has set up a VOIP network in the United States featuring centralized management,
five – digit dialing for calls between offices and employees, hub-based voice mail, and unfield
messaging. With 51 offices and 2,800 employees nationwide, “We really wanted our geographically
dispersed sales teams to be able to communicate more quickly and easily, enabling us to provide
faster, more flexible service,” says Kevin Lopez, national manager of telecommunications at Grant
Thornton.
The new network has been in place since last spring. Grant Thornton has cut communication
costs by routing voice traffic over its wide-area ...yees use the internal
audioconferencing capability. Over the next four years, Wetzel estimates that H.B. Fuller will save
about $2 million because of its VOIP investment.
1. What are the main business benefits that can be gained by companies that switch to VOIP
telephone systems?
2. What are some of the major cost factors that may limit a positive rate of return from investment
in VOIP projects?

1. What can be done to improve the security of business by using Internet?
2. What role does database management play in managing data as a Business resources?
