It introduces the big ideas of iterative and evolutionary development, agile methods, and a variety of agile and of purely iterative methods: Amazon link Applying UML and Patterns I'm grateful to know that the publishers tell me this the most popular text worldwide for software development.

It is now in about languages and is a standard university text in many countries as an introduction to analysis and design of software-intensive systems.

Functional requirements that indicate what the system will do. Provide a basis for performing tests that verify the system delivers the functionality stated. To analyse what functionality that need developing for the system 18 Use cases documented in craig larman ooad ways Verbal description Describes the content of each use craig larman ooad Typically uses a pre-defined template Use Case diagrams Give an overview of visible use scenarios in the system Describes what actors that interact with the system Describes any linkages between use cases 19 Use Case Formats verbal description Brief Terse one-paragraph summary, usually the main success scenario.

Polymorphism in object-oriented programming According to polymorphism principle, responsibility of defining the variation of craig larman ooad based on type is assigned to the type for which this variation happens.

This is achieved using polymorphic operations. The user of the type should use polymorphic operations instead of explicit branching based on type. Service systems architecture A pure fabrication is a class that does not represent a concept in the problem domain, specially made up to achieve low coupling, high cohesion, and the reuse potential thereof derived when a craig larman ooad presented by the information expert pattern does not.
