c＃sql查詢問題

Question

這是OCR。我的系統允許用戶輸入一個由字符組成的圖像，填入特定的字符和描述。輸入數據將被插入到數據庫中。這是我的問題，如果用戶想要輸入具有相同字符但字體不同的圖像，則不需要重新輸入字符以及描述。他們可能只需要使用導入按鈕，它可以導入現有的圖像，讓系統知道兩個字符是相同的。因此，當用戶輸入要掃描的系統圖像時，系統可能會知道不同字體的字符。

那麼我如何編寫系統來通知系統，當用戶導入現有的字符是相同的？

原諒我，如果我誤解了你的問題，但似乎你需要一個多表數據庫做

一個例子

1. 用戶+字體細節（我不明白什麼字體細節）
2. 上傳詳細信息，例如掃描的項目

在數據庫方面，它也許更有用做

1. 用戶
2. 圖像細節
3. 鏈接USER_ID之間image_id

除了復位描述和人物等，你可以做的是詢問他們是否想要基於相同的圖像插入另一個。

我沒有真正理解這個的字體部分。
