Frieda Bannister is the IT manager for the state of Iowas Department of Transportation (DOT). She is interested in finding ways to reduce the costs of operating the DOTs vehicle repair facilities. These facilities purchase replacement parts and repair supplies for all of the states cars, trucks, construction machinery, and road maintenance equipment. Frieda has read about XML and thinks that it might help the DOT send orders to its many suppliers throughout the country more efficiently. Use the Online Companion links, the Web, and your library to conduct research on the use of XML in state, local, and federal government operations. Provide Frieda with a report of about 500 words that includes sections that discuss what XML is and explain why XML shows promise for the ordering application Frieda envisions. Your report should also identify other DOT business processes or activities that might benefit from using XML. The report should also include a summary of the main disadvantages of using XML today for integrating business transactions. End the report with a brief statement regarding how the W3C Semantic Web project results might help the DOT operate more efficiently in the future.
