c #sql查询问题

Question

这是OCR。我的系统允许用户输入由字符组成的图像，填写特定字符和描述。输入数据将插入数据库。这是我的问题，如果用户想要输入具有相同字符但是使用不同字体的图像，则不需要重新键入字符和描述。他们可能只需要使用导入按钮来导入现有图像，让系统知道两个字符是否相同。因此，当用户输入图像供系统扫描时，系统可能知道不同字体的字符。

然后我如何编码系统以通知系统当用户导入现有字符时该字符是相同的？

Answer 1

请原谅我，如果我误解了你的问题，但似乎你需要一个多表数据库才能做到这一点

一个例子

1. 用户+字体详细信息（我不明白字体的详细信息）
2. 上传详情，例如扫描项目

就数据库而言，执行

可能更有用
1. 用户
2. 图片详情
3. user_id和image_id之间的链接

您可以做的是询问他们是否要根据同一图像插入另一个，而不是重置描述和字符等。

我并没有真正理解它的字体部分。
