Designing OO software is hard Even harder to design reusable OO software Experienced designers make good design New designers tend to fall back on non-oo techniques used before Experienced designers know something what is it? Expert designers know not to solve every problem from scratch They reuse solutions Design patterns make OO designs more flexible, elegant, and ultimately reusable Telenovela also makes good use of repetitive patterns 4. Program to an interface, not an implementation. Favor object compositions over class inheritance. Black-box reuse. A common enterprise data Supporting multiple views e. Define one interface for querying, and one interface for manipulation

Software Pioneers pp Cite as. We propose design patterns as a new mechanism for expressing object-oriented design experience. Design patterns identify, name, and abstract common themes in object-oriented design. They capture the intent behind a design by identifying objects, their collaborations, and the distribution of responsibilities. Design patterns play many roles in the object-oriented development process: they provide a common vocabulary for design, they reduce system complexity by naming and defining abstractions, they constitute a base of experience for building reusable software, and they act as building blocks from which more complex designs can be built. Design patterns can be considered reusable micro-architectures that contribute to an overall system architecture. We describe how to express and organize design patterns and introduce a catalog of design patterns.

Он всегда поощрял сотрудников к анализу и прояснению всяческих нестыковок в каждодневных делах, какими бы незначительными они ни казались. И вот теперь он требует, чтобы они проигнорировали целый ряд очень странных совпадений. Очевидно, директор что-то скрывает, но Бринкерхоффу платили за то, чтобы он помогал, а не задавал вопросы. Фонтейн давно всем доказал, что близко к сердцу принимает интересы сотрудников.

Сьюзан встала и быстро подошла к громадному книжному шкафу с техническими руководствами, взяла с полки справочник с прошитым проволочной спиралью корешком и принялась его листать. Она нашла то, что искала, вернулась со справочником к своему терминалу, ввела несколько команд и подождала, пока компьютер проверит список команд, отданных за последние три часа. Сьюзан надеялась обнаружить внешнее воздействие - команду отключения, вызванную сбоем электропитания или дефектным чипом.
