      What is the difference between a class diagram and an ERD

      A class diagram can include operation/functions as well as attributes/data.

      How to estimate the time to program a project

      This is possible on small projects. Large projects make it harder. Unkowns and risks make it hard to estimate accurately. The best practice is to use experience from previous similar projects, and allow a generous safety factor.

      This won't be on the final.

      How to show attributes of relations in an UML diagram

      There is the easy way --make the relation a class...

      A more complex technique is to attach a class to the line with a dotted line and put the attributes in the line.

      Or you can use a tiny little "Chen" diamond and add a dotted line to a class that lists the attributes.

      I drew this [ costbenefit2012.jpg ] in class... I drew this [ costbenefit2012.jpg ] in class...
