Session Six: Data Modeling for Integration

Objectives:

• What is data modeling
• Data integration from a data model perspective
• Why is data integration hard
• What is XML
• XML and data integration
• Questions for vendors

Readings:

• Weil, J., "Companies Pollute Earninges Reports, Leaving P/E Ratios Hard to Calculate," Wall Street Journal. 21 August 2001 p. A1.

• Skim this article. It is short, fun, and merely meant to convey some intuitions about challenges to data integration.

• Madnick, S., "The misguided silver bullet: What XML will and will not do to help information integration," Sloan Working Paper 4185-01, October 2001.

• Be sure to read Section 2 and Section 5 for an appreciation of problems and what XML does not address.

• Seligman, L. and Rosenthal, A., "XML's Impact on Databases and Data Sharing," IEEE Computer. June 2001 p. 59 - 67.

• Be sure to read from page 63 to page 67 for a nice breakdown of architecture-level data integration challenges.

• Preview to Section 4 - Section 4.2 Rob, P. and Coronel, C., Database Systems Design, Implementation, and Management, 3rd edition, Course Technologies, Cambridge, MA 1997 p. 187 - 197. Skim this for a framework on what data models are and why they are important.

• Preview to Chaper 6 - Chapter 6.3 Manninno, M., Database application development and design, McGraw Hill, Boston, MA 2001 p. 191 - 203.

• Skim this to understand the system-level goals for database development.

• For those not familiar with XML, we recommend: Bosak J. and Bray, T., "XML and the Second-Generation Web," Scientific American, May 1999 (http://www.sciam.com/1999/0599issue/0599bosak.html).

• Walsh, N., "A Technical Introduction to XML," XML.com, October 1998 (http://www.xml.com/pub/a/98/10/guide0.html).
