What are best tools for geodatabase design that can be used in ArcGIS modeling projects ?
Are you looking for documents to supplement the help files? ArcGIS Help (10.2, 10.2.1, and 10.2.2)
No, I am looking for a tool to Create, edit, ... a geodatabase schema.
You may want to check out the ArcGIS Diagrammer - Demonstration Video - YouTube
The ArcGIS 10.1 version is available here, but there should be a version of the tool for ArcGIS 10.0 around somewhere as well. ESRI keeps changing the links to older resources
Thank you Owen
No problem - I haven't used it for a while but ArcGIS Diagrammer was very useful for a project I worked on some time ago.
Which version of ArcGIS are you using?
I am using ArcGIS 10.0
You might want to look into X-Ray for ArcGIS - not sure if it works on 10.0 though.
