+## 重量管理数据表设计
+
+为支持 `http://localhost:4200/weight` 页面在 Parse Dashboard 中展示和操作数据，需要建立以下两个数据表。表格中列出了字段名称、类型、用途以及是否必填，便于快速参考。
+
+### 表一：`WeightRecord`（体重记录）
+
+| 字段名 | 类型 | 描述 | 是否必填 |
+| --- | --- | --- | --- |
+| `objectId` | String | Parse 默认的记录 ID | 是 |
+| `date` | String |      | 是 |
+| `weight` | Number | 体重（kg） | 是 |
+| `bodyFat` | Number | 体脂率（%） | 是 |
+| `muscleMass` | Number | 肌肉含量（kg） | 是 |
+| `measurementTime` | String | 测量时间（HH:mm） | 否 |
+| `measurementCondition` | String | 测量条件：`fasting`（空腹）或 `after_meal`（餐后） | 否 |
+| `notes` | String | 备注 | 否 |
+| `tags` | Array\<String\> | 关键节点标记（如“开始运动”“目标调整”等） | 否 |
+| `createdAt` | Date | Parse 默认的创建时间戳 | 是 |
+| `updatedAt` | Date | Parse 默认的更新时间戳 | 是 |
+| `syncStatus` | String | 同步状态：`synced`（已同步）或 `pending`（待同步） | 否 |
+
+**Parse Dashboard 创建步骤**
+
+1. 在 Browser 中点击 “Create a class”。
+2. 输入 `WeightRecord` 作为类名。
+3. 按照表格添加字段及对应类型。
+
+### 表二：`WeightGoal`（体重目标）
+
+| 字段名 | 类型 | 描述 | 是否必填 |
+| --- | --- | --- | --- |
+| `objectId` | String | Parse 默认的记录 ID | 是 |
+| `targetWeight` | Number | 目标体重（kg） | 是 |
+| `targetBodyFat` | Number | 目标体脂率（%） | 否 |
+| `targetDate` | String | 目标日期（YYYY-MM-DD） | 是 |
+| `startWeight` | Number | 起始体重（kg） | 是 |
+| `startBodyFat` | Number | 起始体脂率（%） | 否 |
+| `startDate` | String | 起始日期（YYYY-MM-DD） | 是 |
+| `weeklyTarget` | Number | 每周目标减重量（kg） | 否 |
+| `createdAt` | Date | Parse 默认的创建时间戳 | 是 |
+| `updatedAt` | Date | Parse 默认的更新时间戳 | 是 |
+| `syncStatus` | String | 同步状态：`synced`（已同步）或 `pending`（待同步） | 否 |
+
+**Parse Dashboard 创建步骤**
+
+1. 在 Browser 中点击 “Create a class”。
+2. 输入 `WeightGoal` 作为类名。
+3. 按照表格添加字段及对应类型。
+
+> 建议：根据业务需要为两张表配置合适的 ACL（读写权限），以保护敏感数据。
