Data Requirements Modeling


If logical and physical data design solutions were documented the way data requirements are currently documented, without the benefit of the graphical representation of a data model, the cumbersomeness of the practices would make it harder and longer to design and verify, and overall a lot more expensive.

Yet, the data modeling of data requirements is not done independently nowadays, if ever, of other types of data modeling. Trying to include it in conceptual or logical modeling forces the combination of designing a solution at the same time or even before the problem space has been fully defined. The systematic reconciliation the data design with the data requirements, element by element, is a manual exercise that is most often not done and will cause the physical data design to go through cycles of readjustments.

Why aren't we building data models that graphically represent and specifically address data requirements? Why can't we automatically reconcile a data model representing the results of the analysis of data requirements with the LDM that represents the proposed logical data design solution? Because the data modeling tools we have now do not facilitate these activities.

François will share the evolution of his thinking on DRM, what he realized and what he proposes. He will share how he sees it being planned and done, and by whom, what changes the modeling tools must incorporate to allow the tool users to benefit fully of the DRM activities, the characteristics he sees in the central model object of DRM: the Logical View, and how different this model object from the Physical View.

François will spend some time in showing how, using specific workarounds, one may be able to create data models that look like DRMs in two different modeling tools.
