Geodatabase -ArcGIS Diagrammer help, add fields to feature class, relationship,

[christinakaras]

I am trying to create a Hydro database using ArcGIS Diagrammer, I have looked at the Hydro models, but there is no 10.0 model.  I am going through the user guide and it is not very useful. 

1) How do I add more fields with detailed information about the fields, to my feature class?
2) When I make a feature dataset am I able to connect it to a Raster Dataset?
3) Do I need to show the relationship between feature classes if they are the same but in different feature datasets?

Where can I find more useful information on this program?

Hi ckaras17,

1) How do I add more fields with detailed information about the fields, to my feature class?
First ensure that the Properties window is opened (View > Properties). Right click on a feature class and select "Add Field". Properties for the newly added field will appear in the Properties window. Modify the name, alias, field type and any other field property.

2) When I make a feature dataset am I able to connect it to a Raster Dataset?
No, raster datasets must be "standalone". That is, they cannot be added to feature datasets.

3) Do I need to show the relationship between feature classes if they are the same but in different feature datasets?
I am not sure if I understand. A relationship must be added to associate any two feature classes (or tables). Non-geodatabase linking is also possible in ArcMap using relates and joins.

Where can I find more useful information on this program?
Have a look at these tutorials.
