What can these two diagrams (entity relationship or relationship schema) be called?
In a database I have produced two types of diagrams as described below:
1. In Object Browser window, under the database name, right-click on Database Diagram and select New Database Diagram to build the first diagram.
2. Click on Query/Design Query in Editor… from the menu to bring up Query Designer and Add Table interfaces. After adding the table form Add Table interface, they will appear with their relational links drawn. See the second image/
Q1: Is there any other way to produce diagram 1 or diagram 2?
Q2: Is there any other type of diagram could be produced showing tables/fields/relations? I guess not but you never know.
Q3: What is the significance of diamond shape (rhombus) in diagram 2?
q4: What is the proper name for each of these two diagrams?
Please ignore file names of these diagrams. I will change them after these question has been answered.
Thank you.

re:> 1.You can right click Your database/table/schema and click create diagram
Is the same as method described for Diagram 1 above (I am using 2008R).
------------
re:> 2.Those diagrams are rightly called ERDs and that how they are called,You can add amount of detail or remove it .
Then what relation schema (diagram) is?
Are you referring adding more or fewer tables by "add amount of detail?"
