Modern software architectures
#1about 5 minutes
Understanding the business impact of software quality
The ISO 9126 model illustrates how neglecting internal quality attributes like maintainability leads to the most expensive and long-term technical debt.
#2about 4 minutes
Differentiating system architecture, software architecture, and design
Software development involves building hierarchical structures, with system architecture defining services, software architecture structuring each service, and software design ensuring sustainable implementation.
#3about 5 minutes
Choosing the right modularization based on scope
Effective modularization depends entirely on the project's scope, which for software architecture is driven by internal quality attributes like analyzability, changeability, and testability.
#4about 4 minutes
Aligning code structure with the business domain
To maintain low complexity and high analyzability, the software's structure should directly mirror the structure of the business domain it represents.
#5about 3 minutes
Applying principles for practical software design
The Single Responsibility Principle and consistent naming patterns are crucial tools for the entire team to create a maintainable and testable software design.
#6about 3 minutes
Decoupling dependencies at every architectural level
Use the Dependency Inversion Principle with contracts or interfaces to systematically decouple dependencies between classes, components, and architectural layers.
