Software EngineeringSoftware Engineering 1. Reuse: Identification of existing solutions • Use of inheritance • Off-the-shelf components and additional solution objects • Design patterns 2. Interface specification • Describes precisely each class interface 3. Object model restructuring • Transforms the object design model to improve its understandability and extensibility 4. Object model optimization • Transforms the object design model to address performance criteria such as response time or memory utilization. Object Design lectures Mapping Models to Code lecture
