+## 0. 友情提示
+
+在 `sql/tools` 目录下，我们提供一些数据库相关的工具，包括测试数据库的快速启动、MySQL 转换其它数据库等等。
+
+注意！所有的操作，必须在 `sql/tools` 目录下执行。
+
+## 1. 测试数据库的快速启动
+
+基于 Docker Compose，快速启动 MySQL、Oracle、PostgreSQL、SQL Server 等数据库。
+
+注意！使用 Docker Compose 启动完测试数据后，因为会自动导入项目的 SQL 脚本，所以可能需要等待 1-2 分钟。
+
+### 1.1 MySQL
+
+```Bash
+docker compose up -d mysql
+```
+
+#### 1.2 Oracle
+
+```Bash
+docker compose up -d oracle
+```
+
+暂不支持 MacBook Apple Silicon，因为 Oracle 官方没有提供 Apple Silicon 版本的 Docker 镜像。
+
+### 1.3 PostgreSQL
+
+```Bash
+docker compose up -d postgres
+```
+
+### 1.4 SQL Server
+
+```Bash
+docker compose up -d sqlserver
+# 注意：启动完 sqlserver 后，需要手动再执行如下命令，因为 SQL Server 不支持初始化脚本
+docker compose exec sqlserver bash /tmp/create_schema.sh
+```
+
+暂不支持 MacBook Apple Silicon，因为 SQL Server 官方没有提供 Apple Silicon 版本的 Docker 镜像。
+
+### 1.5 DM 达梦
+
+① 下载达梦 Docker 镜像：https://download.dameng.com/eco/dm8/dm8_20230808_rev197096_x86_rh6_64_single.tar
+
+② 加载镜像文件，在镜像 tar 文件所在目录运行：
+
+```Bash
+docker load -i dm8_20230808_rev197096_x86_rh6_64_single.tar
+````
+
+③ 在项目 `sql/tools` 目录下运行：
+
+```Bash
+docker compose up -d dm8
+# 注意：启动完 dm 后，需要手动再执行如下命令，因为 dm 不支持初始化脚本
+docker compose exec dm8 bash -c "exec /opt/dmdbms/bin/disql SYSDBA/SYSDBA001 \`/tmp/schema.sql"
+exit
+```
+
+**注意**: `sql/dm/ruoyi-vue-pro-dm8.sql` 文件编码必须为 `GBK` 或者 `GBK` 超集，否则会出现中文乱码。
+
+暂不支持 MacBook Apple Silicon，因为 达梦 官方没有提供 Apple Silicon 版本的 Docker 镜像。
+
+## 1.X 容器的销毁重建
+
+开发测试过程中，有时候需要创建全新干净的数据库。由于测试数据 Docker 容器采用数据卷 Volume 挂载数据库实例的数据目录，因此销毁数据需要停止容器后，删除数据卷，然后再重新创建容器。
+
+以 postgres 为例，操作如下：
+
+```Bash
+docker compose down postgres
+docker volume rm ruoyi-vue-pro_postgres
+```
+
+## 2. MySQL 转换其它数据库
+
+### 2.1 实现原理
+
+通过读取 MySQL 的 `sql/mysql/ruoyi-vue-pro.sql` 数据库文件，转换成 Oracle、PostgreSQL、SQL Server 等数据库的脚本。
+
+### 2.2 使用方法
+
+① 安装依赖库 `simple-ddl-parser`
+
+```bash
+pip install simple-ddl-parser
+# pip3 install simple-ddl-parser
+```
+
+② 执行如下命令打印生成 postgres 的脚本内容，其他可选参数有：`oracle`、`sqlserver`、`dm8`：
+
+```Bash
+python3 convertor.py postgres
+# python3 convertor.py postgres > tmp.sql
+```
+
+程序将 SQL 脚本打印到终端，可以重定向到临时文件 `tmp.sql`。
+
+确认无误后，可以利用 IDEA 进行格式化。当然，也可以直接导入到数据库中。
