Modeling Tools
Use Case	A semi-formal description of what a user wants from a system and how they expect to interact with the system to bring about a specific result. Generally people; however, a user can also be another system or another piece of the same system. Sometimes referred to as scenarios. Roles before Objects by Doug Lea Dealing with Roles(PDF) by Martin Fowler
CRC	Class-Responsibility-Collaboration cards. Martin Fowler calls it "One of the most valuable techniques for learning OO" (UML Distilled p9) A Laboratory For Teaching Object-Oriented Thinking by Ward Cunningham and Kent Beck, the developers of CRC.
Interaction Diagrams	Two flavours: sequence and collaboration. Useful when trying to capture the behaviour of several objects within a single use case. Martin Fowler recommends using State diagrams to model the behaviour of one object across multiple use cases. (UML Distilled p78)
Class Diagrams	Classes describe objects in the domain and the static relationships that exist between them. Detail the class data (attributes) and operations (behaviour). UML Tutorial - Class Diagrams(PDF) by Robert C. Martin Class Diagrams in Analysis an exercise in developing Class Diagrams from a Use Case accompanied by lecture notes (PDF) which explain the analysis process.
Design Patterns	Patterns are example models of processes that crop up repeatedly in software development. For example, developers are often faced with problems that require moving through a list or collection. The Iterator pattern describes a standard technique for handling iterations. Implementing Basic Design Patterns in Java by Doug Lea Speaking on the Observer pattern How can you use the Observer pattern in your Java design? (JavaWorld)
