Question:

Consider the following recursive DTD.

<!DOCTYPE parts [

<!ELEMENT part (name, subpartinfo*)>

<!ELEMENT subpartinfo (part, quantity)>

<!ELEMENT name ( #PCDATA )>

<!ELEMENT quantity ( #PCDATA )>

] >

a. Give a small example of data corresponding to the above DTD.

b. Show how to map this DTD to a relational schema. You can assume that part names are unique, that is, whereever a part appears, its subpart structure will be the same.
