The aspects that are more of a domain-related nature and those that are more of a technical nature are as follows:

More technical:

Choosing a database (A)

Choosing a layout manager in a GUI (D)

The average number of methods per class (E)

More domain-related:

Modelling a banking account (B)

Legal constraints for the execution of a money transfer ©

Specification of a calculation formula (F)

In software architecture, aspects can be categorized based on their relevance to the domain (the problem space) or the technology (the solution space). Here’s an explanation of each:

More Technical:

Choosing a database (A): This is a technical decision based on factors like data volume, concurrency, performance, and technology stack.

Choosing a layout manager in a GUI (D): This involves technical considerations about how user interface elements are arranged and managed on the screen.

The average number of methods per class (E): This is a technical metric used in object-oriented design to assess complexity and maintainability.

More Domain-Related:

Modelling a banking account (B): This involves understanding the business rules and operations of banking accounts, which is domain-specific knowledge.

Legal constraints for the execution of a money transfer ©: These are domain-related as they pertain to the legal and regulatory requirements of financial transactions.

Specification of a calculation formula (F): This is typically domain-related because it involves the business logic and rules for performing calculations within the domain.

These distinctions are important for architects to consider when making design decisions, ensuring that both technical and domain-related aspects are adequately addressed.
