+## CURD(快速增删改查)
+
+大部分的后台管理系统，或者API服务都是对数据进行管理，所以可以看到大量的CRUD场景(增删改查)，cool-admin对此进行了大量地封装，让这块的编码量变得极其地少。
+
+
+#### 新建一个数据表
+
+`src/modules/demo/entity/goods.ts`，项目启动数据库会自动创建该表，无需手动创建
+
+```ts
+import { EntityModel } from '@midwayjs/orm';
+import { BaseEntity } from 'midwayjs-cool-core';
+import { Column } from 'typeorm';
+
+/**
+ * 商品
+ */
+@EntityModel('demo_app_goods')
+export class DemoAppGoodsEntity extends BaseEntity {
+
+    @Column({ comment: '标题' })
+    title: string;
+
+    @Column({ comment: '图片' })
+    pic: string;
+
+    @Column({ comment: '价格', type: 'decimal', precision: 5, scale: 2 })
+    price: number;
+
+}
+
+```
+
+#### 编写api接口
+
+`src/modules/demo/controller/app/goods.ts`，快速编写6个api接口
+
+```ts
+import { Provide } from '@midwayjs/decorator';
+import { CoolController, BaseController } from 'midwayjs-cool-core';
+import { DemoAppGoodsEntity } from '../../entity/goods';
+
+/**
+ * 商品
+ */
+@Provide()
+@CoolController({
+  api: ['add', 'delete', 'update', 'info', 'list', 'page'],
+  entity: DemoAppGoodsEntity
+})
+export class DemoAppGoodsController extends BaseController {
+
+}
+```
+
+这样我们就完成了6个接口的编写，对应的接口如下：
+
+- `POST /app/demo/goods/add` 新增
+- `POST /app/demo/goods/delete` 删除
+- `POST /app/demo/goods/update` 更新
+- `GET  /app/demo/goods/info` 单个信息
+- `POST /app/demo/goods/list` 列表信息
+- `POST /app/demo/goods/page` 分页查询(包含模糊查询、字段全匹配等)
+
+
