DataModel.Org ~ A place to find out about data modelling

Scott McManus writes

This website provides a good overview and introduction to the Mystical world of datamodeling, symbology and cardinality. It explains the reasons why we would want to normalise our data and the levels of normalisation and what they do in simply easy to understand language and has some good diagrams that would normally be used in an Entity Relationship Diagram. It is not a pretty web site and has not been updated often. But then the topic is fairly static, it also provides a list of relevant texts one can source that will further explain Normalisation. I like this introductory book on Database management with a bonus that it uses MS access as its explanation tool.
