Concerning external interfaces, Postel's law suggests: "Be conservative in what you do, be liberal in what you accept from others." Assume that Postel's law has been consistently applied in your system. (Assign all answers.)
정답:
Explanation:
A) FalseB) FalseC) FalseD) TrueE) TrueF) False
Postel's law, also known as the robustness principle, is a guideline in software engineering that advises to "be conservative in what you do, be liberal in what you accept from others"1. This principle has implications for system design and interaction with external interfaces:
A) Response time of the system is reduced: This is false. Postel's law does not directly relate to the response time of a system1.
B) Implementation effort increases: This is false. Being liberal in what is accepted can actually simplify implementation because the system is designed to handle a wider range of inputs without failure1.
C) Usability of the system is reduced: This is false. Postel's law aims to increase robustness and interoperability, which can enhance usability by making the system more resilient and accommodating1.
D) Robustness of the system is increased: This is true. By being conservative in outputs and liberal in inputs, the system becomes more robust, handling a variety of inputs without error1.
E) The integrity of the data transferred via interfaces is increased: This is true. Accepting a wide range of inputs and adhering strictly to output specifications helps maintain data integrity across different systems1.
F) Availability of the system is reduced due to potentially bad quality of input data: This is false. Postel's law suggests that the system should be designed to handle poor quality input data gracefully, thus maintaining availability1.
Applying Postel's law helps create systems that are more tolerant of input variations and strict in their outputs, contributing to overall system robustness and reliability1.
Which information is presented in the building-block view? Rate the alternatives below as either true or false.
(Assign all answers.)
(Assign all answers.)
정답:
Explanation:
A) TrueB) FalseC) TrueD) FalseE) True
The building-block view, as per the iSAQB SOFTWARE ARCHITECTURE - FOUNDATION LEVEL, typically includes the following information:
A) Which building blocks the software is composed of: This is true. The building-block view shows the composition of software building blocks1.
B) How the building blocks interact during run time: This is false. The interaction during runtime is typically shown in the runtime view, not the building-block view1.
C) How the building blocks are hierarchically decomposed: This is true. The building-block view includes hierarchical decomposition of the software building blocks1.
D) How the building blocks are distributed in a distributed system: This is false. The distribution of building blocks in a distributed system is part of the deployment view1.
E) The dependencies between the building blocks: This is true. The building-block view should show the dependencies between the different building blocks1.
These aspects are essential for understanding the structure and organization of the software architecture and are aligned with the iSAQB SOFTWARE ARCHITECTURE - FOUNDATION LEVEL documents1.
