# Dynamic In-Database Modeling
**动态库内建模**是 NeurIDA 提出的新范式,核心思想是**从「为每个任务训练固定模型」转向「在查询时从共享组件装配定制模型」**
## 范式对比
| 维度 | 静态建模(传统) | 动态建模NeurIDA |
|------|----------------|-------------------|
| 模型生命周期 | 训练→部署→固定 | 查询时按需装配 |
| 任务覆盖 | 一对一(每个任务一个模型) | 一对多(共享架构覆盖所有任务) |
| 数据操作 | 需提取、预处理、外移 | 数据库内直接操作 |
| 适应性 | 新任务需从头构建 pipeline | 即时适配新任务 |
## 实现机制
依托 [[composable-base-model-architecture|可组合基础模型架构]]:预训练一组异构基础模型 + 共享模型组件(统一元组编码器、关系消息传递模块、上下文融合模块)。查询时 [[dime-dynamic-in-database-modeling-engine|DIME]] 根据任务画像从池中动态选取和配置组件。
