項目進度管理系統(tǒng)源代碼

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

首先，讓我們來看一下項目進度管理系統(tǒng)的需求。項目進度管理系統(tǒng)需要包括以下功能：

1. 項目進度查詢：開發(fā)人員可以查詢項目的當(dāng)前進度、計劃進度、實際進度等信息。
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. 進度報表：開發(fā)人員可以生成各種項目進度報表，如進度趨勢圖、任務(wù)分布圖等。
4. 權(quán)限管理：開發(fā)人員可以對用戶進行權(quán)限管理，包括對用戶的訪問權(quán)限、修改任務(wù)權(quán)限等。

接下來，我們來看一下項目進度管理系統(tǒng)的源代碼。這個系統(tǒng)使用了Python的Flask框架和MySQL數(shù)據(jù)庫來存儲項目進度數(shù)據(jù)。
