Hello everyone:
I am writing a cocoa program that interfaces to my websites
database. There are three tables in the database: topic, author,
articles. There is a many to one relationship between the articles
and the topic as well as the articles and the author table. I
created a class that represents each of the tables and then created
one global NSMutableArray to hold all the articles and two global
NSMutableDictionaries to hold the topics and authors. However, I
want to add a gui to this later and use bindings.
However, I don't understand how I am going to be able to keep
the links between the articles table and the other two tables. I
have attached the project files stripped of the database code to show
you what I am trying to. Thanks for any help.
Sincerely,
Michael Petnuch
