Business Milestones and Data Models – an Introduction to Entity Life Histories
George McGeachie, Metadata Matters
Your data models describe the ‘things’ of interest to your business. Some of those ‘things’ pass through a number of recognizable states, and it’s critical that you understand the actions that cause those changes in state, and the business rules that must be satisfied. There’s a simple phrase for describing the analysis approach required – it’s “Entity Life History” analysis. There are several notations in use, and the techniques have existed for decades.
Find out more about why and how to construct Entity Life Histories, and the problems that they can help you avoid. Participate in the construction of simple Entity Life Histories, and examine how you can get your modeling tools to help you.
