Software Architecture and Design Patterns

Software Architecture and Design Patterns is a core discipline within software engineering focused on the strategic, high-level organization of a software system and the tactical solutions for common problems within it. Software architecture involves defining the fundamental structure, components, and their interactions to meet key quality attributes such as performance, security, and maintainability. Complementing this macro-level blueprint, design patterns provide proven, reusable templates—like the Singleton, Factory, or Observer patterns—for solving recurring, lower-level design challenges. By mastering both architecture and patterns, engineers can effectively manage complexity, promote code reusability, and construct robust, scalable, and maintainable software systems.
