  • 领域层（Domain）：定义了 School 实体类和 SchoolRepository 抽象基类，明确了业务实体和数据访问的契约。
  • 基础设施层（Infrastructure）：通过 SQLAlchemy 实现了 SchoolRepository 类，负责与 SQLite 数据库进行交互，包括增删改查操作。
  • 应用层（Application）：SchoolService 类封装了业务逻辑，调用 SchoolRepository 接口的方法完成具体的业务操作。
  • 表现层（Presentation）：
    • SchoolView 类负责创建和管理用户界面，包括搜索框、ttk.Treeview 表格、操作按钮和分页按钮。
    • SchoolController 类处理用户的操作请求，调用 SchoolService 完成相应的业务逻辑，并更新视图。
