📚 Year 10 SQA Computing: Case Study Practice | 苏格兰 SQA 十年级计算机：案例分析实战演练
In SQA Computing Science, case studies allow you to apply your knowledge of analysis, design, development and testing to a realistic scenario. They test your ability to think like a software engineer, breaking down problems and creating effective digital solutions.
在 SQA 计算机科学中，案例分析让你将分析、设计、开发与测试的知识应用于真实场景。它考验你像软件工程师一样思考的能力，分解问题并创建有效的数字解决方案。
1. Understanding the Case Study Approach | 理解案例分析的方法
Case studies in the SQA curriculum are not just about coding; they follow a structured software development cycle. The process typically moves through stages: analysis, design, implementation, testing and evaluation. Each stage requires careful documentation to show your understanding.
SQA 课程中的案例分析不仅仅是编码，它遵循结构化的软件开发周期。这个过程通常经历几个阶段：分析、设计、实施、测试和评估。每个阶段都需要详细的记录来展示你的理解。
To succeed, you must demonstrate computational thinking skills such as abstraction (focusing on essential features), decomposition (splitting the problem into smaller parts) and algorithmic thinking (designing step-by-step solutions). These form the foundation of any good case study answer.
要想成功，你必须展示计算思维技能，例如抽象化（关注关键特征）、分解（将问题拆分成更小的部分）和算法思维（设计逐步的解决方案）。这些构成了任何优秀案例分析答案的基础。
In the exam or assignment, you will often be asked to identify inputs, processes and outputs, create a database structure, write pseudocode and design tests. Always relate your response back to the specific scenario given.
在考试或作业中，你往往被要求识别输入、处理过程和输出，创建数据库结构，编写伪代码并设计测试。始终将你的回答与给出的具体场景联系起来。
2. Case Study Scenario: Library Book Management System | 案例场景：图书馆书籍管理系统
Imagine you are developing a digital system for a small school library. Currently, the library uses a paper-based log to track book loans. The librarian wants software that can: add new books to the catalogue, allow pupils to borrow and return books, search for a book by title or author, and display which books are currently on loan.
设想你正在为一所小型学校图书馆开发一个数字化系统。目前，该图书馆使用纸质记录来跟踪图书借阅。管理员希望软件可以：向目录中添加新书，允许学生借阅和归还书籍，按书名或作者搜索图书，并显示当前有哪些书被借出。
Functional requirements: the system must validate pupil IDs, prevent borrowing if a book is unavailable, and calculate due dates automatically. Non-functional requirements: the system should respond within two seconds and be easy for staff with basic IT skills to use.
功能需求：系统必须验证学生 ID，如果图书不可借则阻止借阅，并自动计算到期日。非功能需求：系统应在两秒内响应，并且便于只有基本 IT 技能的员工使用。
By framing the task as a real-world problem, you can more easily identify
