一、软件介绍

今天给大家分享我自己编写的数据库表结构文档生成工具，方便大家在实际开发当中，可以很方便导出业务系统的表结构，也可以作为项目验收文档中数据库设计文档使用。这样可以大大减少编写数据库表结构文档的时间，有需要的朋友欢迎下载或者沟通交流！

二、技术框架

• 编程语言：C# （ Net Framework4.5.5）
• 数据库技术框架：Dapper
• 导出Word文档：NPOI
• 访问方式：WinForm窗体应用程序，Windows操作系统可以直接运行

三、功能介绍

• 支持SQLServer、MySQL（5.7、8.0）、SQLite 三种类型的数据，持续更新
• 支持Word、Html、MarkDown 三种格式的导出
• 导出内容包含数据表（字段详情、字段注释、长度、默认值等）、创建表脚本、视图及视图脚本、存储过程及脚本
• 支持生成文档的同时直接打开文档
• 支持数据库备份（目前只支持SQLServer导出bak备份文件）

四、代码展示
