On Wednesday, 1 December 2010 I’ll be speaking three times at the Ohio Enterprise Modeling User Group:

10 AM ET

Classic Data Modeling Mistakes & How to Avoid Them

We’ve all been there: a shortcut here, a compromise there, an over-modeling over there. In this presentation, Karen demonstrates classic and all-too-common data modeling mistakes that are easy to make and yet just as easy to avoid. We’ll look at data modeling generalizations, applying surrogate keys, understanding the difference between design and business requirements, data model changes, flags, and sharing data models.

11 AM ET

Modeling Global User Community Webcast: Normalization of Social Networking in the ERwin Community

In this webcast, panelists discuss social networking from an ERwin data professional perspective. Facebook, InfoAdvisors, LinkedIn, Twitter, My CA, ERwin.com, and data-centric tool social networks offer many options for you to join a virtual data community. If you are new to social networking, a seasoned tweeter, or just want to use social networking more efficiently, this webcast is ideal for you.

  • Social Networking 101
  • Deeper Dive / Benefits for Data Professionals
  • Security / Personal and Professional Boundaries
  • “Why Be Normal?”


Data Modeling Contentious Issues

A highly interactive session for seasoned modelers, attendees evaluate the options and best practices of common and advanced data modeling issues, such as:

  • Party/party role
  • Natural vs. surrogate keys
  • Varchar Minimums
  • Identity Crisis
  • SOAs, Ontologies, ESBs, New TLAs and Shoe Strings
  • What is Logical? What is Physical? Why Do We Care?
  • Politics vs. Customer Satisfaction

Participants in this session will be presented with an issue along with a range of responses or possible solutions. We will vote on preferred response, then the group as a whole will discuss the results, along with the merits of each possible response. The goal of this workshop is to help practitioners identify potential points of conflict in data modeling, as well as alternative approaches to resolving the issues.

During the event there is a presentation by Donna Burbank about upcoming release of ERwin v8.

I hope to see you there.
