## 2. 当前问题分析
### 2.1 命名不一致问题
| 问题类别 | 具体表现 | 影响 |
|---------|---------|------|
| **前缀混乱** | `basic_*`, `side_*`, `util_*`, `eco_*`, `pace_*`, `rd_*`, `special_*`, `timing_*` | 无法从名称直观判断归属维度 |
| **冗余命名** | `basic_avg_headshot_kills` vs `basic_headshot_rate` | 一个是总数,一个是比率,命名规则不统一 |
| **缩写不统一** | `FK` vs `First Kill`, `HS` vs `Headshot`, `Avg` vs `Average` | 可读性差 |
| **中英混杂** | 数据库用英文,但UI标签用中文 | 维护困难 |
### 2.2 数据重复与冗余
| 重复类型 | 示例 | 问题 |
|---------|------|------|
| **同一指标多处展示** | `basic_avg_rating`同时出现在Dashboard和Detailed Panel | 数据冗余展示 |
| **相似指标并存** | `timing_early_aggression_rate` vs `rd_phase_kill_early_share` | 实际都是"前30秒击杀占比" |
| **计算结果重复** | `basic_first_kill_rate` 和 `basic_first_death_rate` 必然互补(FK+FD=100%) | 可简化为一个指标 |
| **阵营数据冗余** | T/CT所有指标都有两套,但很多时候差异不大 | UI拥挤,核心信息淹没 |
### 2.3 分类逻辑混乱
| 混乱表现 | 示例 | 理想归类 |
|---------|------|---------|
| **相关指标分散** | 首杀/首死在"Opening Impact",但首杀时间在"PACE - Tempo" | 应统一归入"开局影响力" |
| **维度交叉** | `hps_pressure_entry_rate`(逆风首杀)既属于HPS,又涉及Opening | 应明确主维度 |
| **深浅不分** | `basic_avg_kd`在详细面板,但`eco_kd_ratio`在深层能力 | 同类指标应在同一层级 |
| **特殊指标孤立** | Special Kills单独一个Section,但Knife/Zeus在Combat | 应统一归入"特殊击杀类" |
### 2.4 UI展示问题
| 问题 | 描述 | 影响 |
|-----|------|------|
| **信息密度过高** | Detailed Stats Panel有80+指标紧密排列 | 用户认知负担重,难以聚焦 |
| **缺少层次** | 所有指标平铺,无主次之分 | 核心数据不突出 |
| **视觉疲劳** | 长列表滚动,无分组视觉分隔 | 易忽略关键信息 |
| **无引导逻辑** | 用户不知道该看哪些数据 | 降低产品价值 |
### 2.5 Schema设计问题
| 问题 | 描述 | 改进方向 |
|-----|------|---------|
| **列名过长** | `rd_phase_kill_early_share_ct` 35字符 | 可缩短为`phase_k_early_ct` |
| **类型不统一** | Rate有的存0-1,有的存0-100 | 统一为0-1,前端格式化 |
| **缺少索引提示** | L3表无明确的"核心指标"标识 | 可增加`is_core`标记列 |
| **JSON滥用** | `rd_weapon_top_json`等,查询不便 | 考虑拆表或使用结构化字段 |

## 9. FAQ
### Q1: 为什么要重组?现有结构有什么问题?
**A**: 当前主要问题:
1. **命名混乱**:前缀不统一(`basic_`/`side_`/`rd_`等),难以维护
2. **数据冗余**:同类指标分散在多个Section,用户查找困难
3. **缺乏层次**:120+指标平铺,核心数据不突出
4. **UI拥挤**:信息密度过高,用户认知负担重
### Q2: 重组后会丢失数据吗?
**A**: 不会。我们采用**增量迁移**策略:
1. 创建新表`dm_player_features_v2`,保留旧表
2. 双写一段时间,确保数据一致
3. 灰度切换,可随时回滚
4. 旧表保留3个月作为备份
### Q3: 新分类体系的依据是什么?
**A**: 基于**游戏功能维度**和**用户关注度**:
1. **功能维度**:枪法、开局、残局、道具、经济、节奏等游戏概念
2. **用户关注度**:通过热力图和用户反馈,确定P0/P1/P2/P3优先级
3. **专业意见**:参考职业教练和数据分析师的建议
### Q4: 重组会影响现有功能吗?
**A**: 短期影响最小化:
1. **后端兼容**:`feature_service.py`会提供新旧API同时支持
2. **前端渐进**:先发布新UI,保留旧版入口,收集反馈后完全切换
3. **数据一致**:新旧两套数据会持续对比验证
### Q5: 如何衡量重组效果?
**A**: 关键指标:
1. **用户体验**:页面停留时间、交互深度、反馈评分
2. **性能**:页面加载时间(<2s)、查询速度(<500ms)
3. **数据质量**:覆盖率(>90%)、异常率(<1%)
4. **开发效率**:新增指标开发时间、Bug数量
### Q6: 我能提供反馈吗?
**A**: 当然!反馈渠道:
1. **GitHub Issue**:提交功能建议或Bug报告
2. **Wiki评论区**:讨论数据定义和展示逻辑
3. **内部群组**:实时讨论和快速响应
