For a building block, the characteristics visible only in the whitebox view are:

• Code structure of the building block (D)
• Algorithms used in the building block (E)
• Implementation details for the security requirements of the building blocks (G)

The blackbox view suffices for:

• Public interfaces of the building block (A)
• Test coverage based on unit tests for sub building blocks contained in the building block (B)
• Test coverage based on integration tests ©
• Security requirements of the building blocks (F)

In software architecture, the whitebox view reveals the internal workings of a building block, including its code structure, algorithms, and specific implementation details1. This view is essential when the internal structure and behavior of the component need to be understood or modified.

On the other hand, the blackbox view treats the building block as an opaque entity, focusing on its exposed interfaces and observable behaviors without revealing its internal structure2. This view is sufficient for understanding what the building block does from an external perspective, such as its public interfaces and how well it performs its functions as determined by testing.

Here’s a breakdown of the characteristics:

• Whitebox View:
• Blackbox View:

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

• More technical:
• More domain-related:

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:
• More Domain-Related:

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

In the context of software architecture, certain elements serve as building blocks to structure and organize software systems effectively.

• A: An algorithm is a sequence of steps designed to perform a specific task and can be a critical part of system logic and functionality.
• B: A component is a modular part of a system that encapsulates its contents and whose deployment and versioning can be managed independently.
• D: A class in object-oriented programming encapsulates data for the object and operations that manipulate that data, serving as a blueprint within the architecture.
• H: A package helps organize classes and interfaces that are related functionally, promoting a cleaner and more manageable architecture structure.
