Looking for yourself can pay dividends #PowerDesigner

On Twitter earlier today, I exchanged tweets with Jane Roberts (@redjane) about finding myself in the phone book. Well, now I’ve just found myself on YouTube!

I was actually curious about videos of a different George McGeachie, a retired footballer who’s a tad older than I am, and searched for my name in YouTube. I didn’t find what I was looking for, but I did find a video that had previously been published on mypowerdesigner.com, which SAP closed down years ago; it was recorded at a SAP conference in the Venetian Hotel in Las Vegas.

I thought it had disappeared without trace, but there it is. It’s me (of course), talking about my soon-to-be-published book “Data Modeling Made Simple with PowerDesigner” – this was before the editor suggested drastic re-ordering of the chapters, so my chapter references are wrong, but hey, I’ve re-discovered myself!

Read widely – here are some books data modellers should take a look at

If you’re like me, you’re a book addict. I’ve built up a large library of books related to metadata and data modelling, and also on subjects such as process management, IT service management and mind mapping. When I was working with Steve Hoberman on our recent book, I didn’t want the book to give the impression that data modellers work in isolation, so I went through my library looking for useful material. I thought I’d share some of my findings with others, so here’s a list of books you should take a look at:

  • Business Rule Concepts (Ronald G. Ross, 2009) – read pages 74, 77 about the role of verbs in describing facts. See also Chapter 1 about noun concepts and terms; I especially like the statement that a  “noun or noun phrase…represents merely the tip of an iceberg with respect to meaning”
  • Building Business Solutions: Business Analysis with Business Rules (Ronald G. Ross and Gladys S.W. Lam, 2011) – Read the chapter on Fact Models and how similar these are to Conceptual Data Models – see also my review of this book
  • Data Quality Assessment (Arkady Maydanchik, 2007) – chapter 4 provides an excellent introduction to and a detailed discussion of attribute domains
  • Document Engineering (Robert J. Glushko and Tim McGrath, 2008) – if you’re modelling the data in documents or service messages, you really must read this book
  • Mind Maps for Kids (Tony Buzan, 2003) – OK, it’s aimed at kids, but it’s a great introduction to the topic – look at the use of colour in his mind maps – how can you use colour effectively in your data models?

New TDAN article from me and Steve Hoberman

The Data Administration Newsletter (TDAN) have just published a new article by myself and Steve Hoberman, based on our recent book “Data Modeling Made Simple with PowerDesigner”.

Tools are necessary for data modeling. You can’t avoid having them, but which one suits you? Well, that depends on what you want to do with those tools, where you want to work in the Data Model Pyramid. See the article to find out what we mean.
