Entity-Relationship (ER) data modelling is a critical technique used by data experts to help design new systems, utilize existing systems, and replace old systems. This note describes the different levels of data modelling, as well as its objectives and benefits, provides a brief history of graphical modelling approaches, and focuses on a particular graphical rule set for creating logical data models called Barker notation.
