Notes about the Diagram

• The Head of the Arrow Points to the “Child” Table.

• The Label on the Arrow Indicates the Name of the Column that Establishes the Foreign Key to the “Parent” Table.

• Column Names for Foreign Keys are Formed by Taking the Table Short Name from the Parent Table and Adding the Joining Column Name from the Parent Table– Example: The MONITORS table uses the

SI_SI_ID column to Join to the SITES table• “SI” is the Table Short Name for the SITES

table• “SI_ID” is the name of the column on the SITES

table used to Perform the Join

• The Microscope Icon is used to Show Additional Links to Reference Tables.

• Not All Tables Available in AQS are Displayed in this Diagram. Only Those Considered Widely Used are Displayed.
