DDD w pigułce Modelowanie oprogramowania jest kojarzone z pojęciem programowania dziedzinowego, w skrócie zwanego DDD. Jest to dość nowatorskie podejście do tworzenia architektury oprogramowania, a jego największą zaletą jest wysoka pewność uzyskiwania bardzo dobrych rezultatów. Programiści często błyskawicznie dostrzegają zalety DDD i korzyści płynące ze stosowania odpowiednich narzędzi, stąd technika ta cieszy się coraz większym uznaniem. Dopiero jednak pełne zrozumienie zasad stosowania wzorców projektowych DDD przez wszystkich zaangażowanych w projekt pozwala na osiągnięcie imponujących wyników przy projektowaniu skomplikowanych systemów oprogramowania. Ten zwięzły i czytelnie napisany podręcznik jest przeznaczony dla programistów, ekspertów dziedzinowych, menedżerów, analityków biznesowych, architektów informacji i testerów. Koncentruje się na praktycznej wiedzy niezbędnej do uzyskania pożądanych rezultatów. Wyjaśniono, jak segregować modele dziedzin za pomocą wzorca kontekstu ograniczonego, jak rozwinąć język wszechobecny, a także w jaki sposób zintegrować wiele kontekstów ograniczonych poprzez wykorzystanie relacji zespołowych i mechanizmów technicznych. Co najważniejsze, dowiesz się, jak podejście DDD działa w rzeczywistości i co zrobić, aby jak najszybciej cieszyć się jego zaletami. W książce przedstawiono następujące zagadnienia: wprowadzenie do DDD i zalety tego podejścia do projektowania projektowanie strategiczne DDD integrowanie istniejących systemów w ramach tworzenia nowych aplikacji modelowanie taktyczne - agregaty i zdarzenia dziedziny narzędzia do zarządzania projektami i przyśpieszania prac Narzędzia DDD - ciesz się udanym wdrożeniem!

Even though object-oriented software design enables more easily maintainable code, companies choose C++ as an OO language for its speed. Object-oriented programming in C++ is not automatic – it is crucial to understand OO concepts and how they map to both C++ language features and OOP techniques. Distinguishing your code by utilizing well-tested, creative solutions, which can be found in popular design patterns, is crucial in today’s marketplace. This book will help you to harness OOP in C++ to write better code.Starting with the essential C++ features, which serve as building blocks for the key chapters, this book focuses on explaining fundamental object-oriented concepts and shows you how to implement them in C++. With the help of practical code examples and diagrams, you’ll learn how and why things work. The book’s coverage furthers your C++ repertoire by including templates, exceptions, operator overloading, STL, and OO component testing. You’ll discover popular design patterns with in-depth examples and understand how to use them as effective programming solutions to solve recurring OOP problems.By the end of this book, you’ll be able to employ essential and advanced OOP concepts to create enduring and robust software.
