What are the basic elements of Architectural Description Languages (ADLs), and what is the main practical limitation of ADLs?

Elements: data flow diagrams and entity-relationship models; Limitation: they are not supported by any tools

Elements: classes and methods; Limitation: too verbose for large systems

Elements: components and connectors, with rules for well-formed architectures; Limitation: domain and application specialists find them hard to understand and use

Elements: use cases and scenarios; Limitation: they cannot model non-functional requirements

Correct Answer

Elements: components and connectors, with rules for well-formed architectures; Limitation: domain and application specialists find them hard to understand and use

Explanation

The basic elements of ADLs are components and connectors, and they include rules and guidelines for well-formed architectures. Their main practical limitation is that, because of their specialized nature, domain and application specialists find them hard to understand and use, making it difficult to assess their usefulness in practice.
