Hi, I heard many times people asked for Entity Relationship diagram/Data model for Microsoft Navision. I’ve created one for version 4.0 [:)]. It is also useful for 3.70 and 3.60. I have plans to continue documenting Microsoft Navision. These plans include what-it-does and how-it-does documentation (UML and/or Process Flow diagrams). Please visit http://www.NaviTools.com and let me know what you think about ER diagrams and idea to provide documentation for Navision.
