Data Structure: Data Modeling or XML?
David Hay
President
Essential Strategies, Inc.
Tuesday 4:40pm - 5:40pm
Level: Data Management - Introductory
XML was designed as a way to organize data for the purpose of transmitting data from one place to another. A relational databases is intended to be a way of organizing data for the purposes of storing and managing them. While both technologies are concerned with data structure, their purposes are clearly different, and confusing them (which is often done) is done at a company’s (or a government agency’s) peril.
This presentation will describe the history of data organization, from hierarchical to relational to hierarchical again. This presentation will present an example of the same domain presented as a data model (and its corresponding relational database design) and as an XML schema, showing the information lost in converting from one to the other.
