Business-friendly Data Models – Graham Witt

Video Description

Recorded live at Data Modeling Zone Australia!

If a system is to support an enterprise’s business information requirements, a necessary part of the design process is effective review of the design by appropriate business stakeholders. For such review to be effective, the design documentation provided to those stakeholders (“the business model”) must:

• be understandable
• be complete, i.e. depict all information in which business stakeholders are interested
• not depict any information in which business stakeholders have no interest (“noise”) which distracts or confuses reviewers, reducing review effectiveness.

Logical data models do not meet these criteria, yet most conceptual data models are degenerate logical data models including much noise. This presentation details what should be included in and excluded from a data model to be reviewed by business stakeholders.
