She enjoys doing 'spot the difference' puzzles.There is a difference between happy and sad.What is the difference between these two cakes?
what is the difference between commutative and symmetric properties
In Database Analysis and Design; the relationship in an ERD can only be mandatory or optional between two entities. Mandatory is where both entities must be present, whereas with optional, you don't always need two entities.

In general, the differences are that interface has(1) no fields and(2) no implementation of methodsbut in UML interface may have features (fields), so the difference left is that interface in UML has no implemented methods while abstract class by definition is partially implemented class.
forward engineering: the creation of code from models. reverse engineering: the creation of models from code.

oh my god,, Adam Sandler has an erd!!!??
UML has high learning curve.
Class diagram is UML structure diagram which shows structure of the designed system at the level of classes and interfaces, shows their features, constraints and relationships - associations, generalizations, dependencies, etc.Communication diagram (called collaboration diagram in now obsolete UML 1.x) is an interaction diagram which shows interactions between objects and/or parts (represented as UML lifelines) using sequenced messages in a free-form arrangement.So, the major difference is that class diagram shows static structure of the system while communication (collaboration) diagram shows system behavior as sequenced exchange of messages between objects.
