項(xiàng)目進(jìn)度管理系統(tǒng)源代碼

隨著現(xiàn)代軟件開發(fā)的不斷推進(jìn)，項(xiàng)目進(jìn)度管理已經(jīng)成為了軟件開發(fā)過(guò)程中不可或缺的一部分。一個(gè)高效的項(xiàng)目進(jìn)度管理系統(tǒng)可以幫助開發(fā)人員更好地管理項(xiàng)目進(jìn)度，提高項(xiàng)目質(zhì)量和效率。本文將介紹一個(gè)基于Python語(yǔ)言的項(xiàng)目進(jìn)度管理系統(tǒng)源代碼，供開發(fā)者參考。

首先，讓我們來(lái)看一下項(xiàng)目進(jìn)度管理系統(tǒng)的需求。項(xiàng)目進(jìn)度管理系統(tǒng)需要包括以下功能：

1. 項(xiàng)目進(jìn)度查詢：開發(fā)人員可以查詢項(xiàng)目的當(dāng)前進(jìn)度、計(jì)劃進(jìn)度、實(shí)際進(jìn)度等信息。
2. 任務(wù)管理：開發(fā)人員可以管理任務(wù)，包括添加、刪除、修改任務(wù)和任務(wù)狀態(tài)等。
3. 進(jìn)度報(bào)表：開發(fā)人員可以生成各種項(xiàng)目進(jìn)度報(bào)表，如進(jìn)度趨勢(shì)圖、任務(wù)分布圖等。
4. 權(quán)限管理：開發(fā)人員可以對(duì)用戶進(jìn)行權(quán)限管理，包括對(duì)用戶的訪問(wèn)權(quán)限、修改任務(wù)權(quán)限等。

接下來(lái)，我們來(lái)看一下項(xiàng)目進(jìn)度管理系統(tǒng)的源代碼。這個(gè)系統(tǒng)使用了Python的Flask框架和MySQL數(shù)據(jù)庫(kù)來(lái)存儲(chǔ)項(xiàng)目進(jìn)度數(shù)據(jù)。
