I am continuing my research on Data Modeling. The research builds on my 1991 International E-R Conference paper "Creative Data Modeling: Encouraging Innovation in Data Design" and book "Data Modeling Essentials".

My PhD thesis, completed in 2006, explored whether data modelling was better characterised as analysis or design. Borrowing from a well-known framework used in creativity research, I looked at:

The Process of Data Modelling: Do data modelling methodologies and observed behaviour of data modellers better fit the analysis or design paradigm?

The Products of Data Modelling: Do data modellers faced with a common scenario produce similar or substantially different models?

The People involved in modelling: do they exhibit "styles" as we would expect of designers?

The Culture of modelling: what do academics, practitioners and thought-leaders believe they are doing or describing? What do widely used texts say or assume?

The research outlined below has been undertaken over the past 2 ½ years. Along the way, I am learning a great deal about what practising data modellers think and how they work.

Over 400 practitioners – primarily attendees at workshops and seminars as summarised below – have contributed to this research. (Click here to review the ethics statement for this research).

As I move from data collection to analysis and write-up, I want to meet my commitment to share my results with those contributors and with the practitioner community in general. So, through to mid-2005, when I expect to complete my thesis, I will be progressively posting results in what I hope is a practitioner-friendly form. “Practitioner-friendly” means I'm not dotting all the ‘i's and crossing all the ‘t's as I will in my thesis. And as I review and check results, I'll correct any errors which may have crept in.

I am interested in your feedback – what you think of the results, and any explanations you want to offer. I plan to incorporate such feedback in my thesis. Just email me at graeme@simsion.com.au.
