数据库实体关系图示例 - 部门、角色、用户、菜单、数据源、项目和分析

"以下是一个数据库实体关系图的示例：\n\n\n+---------------------+ +----------------------+\n| Department | | SystemRole |\n+---------------------+ +----------------------+\n| DepartmentID (PK) | | RoleID (PK) |\n| DepartmentName | | RoleName |\n+---------------------+ +----------------------+\n | |\n | |\n | |\n+---------------------+ +----------------------+\n| RolePermission | | SystemUser |\n+---------------------+ +----------------------+\n| RoleID (FK) | | UserID (PK) |\n| PermissionID (FK) | | UserName |\n+---------------------+ | Password |\n | | DepartmentID (FK) |\n | | RoleID (FK) |\n | +----------------------+\n |\n |\n+---------------------+\n| Menu |\n+---------------------+\n| MenuID (PK) |\n| MenuName |\n| MenuURL |\n+---------------------+\n |\n |\n |\n+---------------------+\n| DataSource |\n+---------------------+\n| DataSourceID (PK) |\n| DataSourceName |\n| DataSourceType |\n+---------------------+\n |\n |\n |\n+---------------------+\n| DashboardProject |\n+---------------------+\n| ProjectID (PK) |\n| ProjectName |\n| ProjectDescription |\n+---------------------+\n |\n |\n |\n+---------------------+\n| ETLProject |\n+---------------------+\n| ProjectID (PK) |\n| ProjectName |\n| ProjectDescription |\n+---------------------+\n |\n |\n |\n+---------------------+\n| AnalysisProject |\n+---------------------+\n| ProjectID (PK) |\n| ProjectName |\n| ProjectDescription |\n+---------------------+\n |\n |\n |\n+---------------------+ +----------------------+\n| AnalysisData | | AnalysisMethod |\n+---------------------+ +----------------------+\n| DataID (PK) | | MethodID (PK) |\n| DataName | | MethodName |\n| DataType | | MethodDescription |\n+---------------------+ +----------------------+\n\n\n该图展示了各个表之间的关系，例如：\n- SystemUser 表中的 DepartmentID 和 RoleID 分别关联到 Department 表和 SystemRole 表。\n- RolePermission 表中的 RoleID 和 PermissionID 分别关联到 SystemRole 表和 Permission 表 (假设存在 Permission 表)。\n- DashboardProject, ETLProject 和 AnalysisProject 表都包含 ProjectID，表明它们可能共享相同的项目信息。\n- AnalysisData 表可能关联到 AnalysisMethod 表，用于存储分析数据及其对应的方法。\n\n您可以根据自己的需求对该图进行调整和扩展。\n\n"
