DAMA Session - XML vs Relational Modeling - Norman Daoust 

Register Now!

As data management practitioners we are very familiar with entity relationship models, but lo and behold there is a new kid on the block: XML models! There are a lot more XML models, and they are becoming ubiquitous. Plus, most of them are not created by data modelers.

In this presentation we'll examine these two types of models from various perspectives. We'll compare the graphical formats of entity relationship models and XML models, look at the target audiences for each, examine the advantages and disadvantages of each, consider appropriateness of usage of both types of models for database design, message design, and services design, compare datatypes for both XML models and entity relationship data models, and examine criteria for determining which to create: an entity relationship model, one or more XML models, or perhaps both!

We'll also review a technique for deriving an XML model from an entity relationship data model.

The presentation will include example XML models contributed by DAMA Phoenix members. And, of course, we'll allow plenty of time for questions and thought provoking discussions!

Attendees will learn:
- The similarities and differences between entity relationship data modeling and XML modeling
- Appropriate usages for data modeling and XML modeling techniques
- Advantages and disadvantages of both entity relationship data modeling and XML modeling
- Criteria for determining which to create

Who should attend:
- Application Programmers and Designers
- Business Analysts
- Data Architects
- Database Programmers and Designers
- Data Modelers
- Enterprise Architects
- Enterprise Data Architects
- SOA Architects
- XML Practitioners

Speaker Biography:

Norman Daoust started his consulting company, Daoust Associates, www.DaoustAssociates.com, in 2001. He specializes in data modeling and healthcare data integration.

Norman has been heavily involved with the creation of the healthcare industry standard data model, the HL7 Reference Information Model (RIM), since its inception. That data model is used to derive the organization’s XML-based messages that are used around the world for healthcare electronic data exchange. Several of his consulting projects have involved creating a presentation or webinar to illustrate the derivation of messages from a data model.

He is a frequent speaker at national and regional conferences and local meetings. His book, UML Requirements Modeling for Business Analysts, describes a way of utilizing the Unified Modeling Language (UML) to improve business analysis.

Norman thrives on data integration projects that most other people avoid!
