How do collaboration patterns compare to design patterns?
Index The goal of the collaboration patterns is knowledge representation using object think principles: personification, first-person think, localized decision-making, and encapsulation. Collaboration patterns help quickly model a business domain by identifying the objects, object relationships, and business rules, and distributing the business services among objects. The resulting model is easily understandable by the domain experts as well as by developers, and the model still exhibits good object model characteristics such as extensibility, and scalability. Design patterns enforce design goals such as reuse, efficiency, and pluggability. Because they extract properties, business services and rules into abstract reusable objects, design patterns vastly increase the size and complexity of the object model, which in turn decreases the understandability for non-technical domain experts. Use collaboration patterns to create an analysis object model that is understandable by domain expert
