?專案型別：JAVA WEB專案
專案名稱：基于Jsp+Servlet的教師科研成果申報系統

用戶型別：3個角色（管理員+教師+審批人）
系統型別：后臺管理系統
設計模式：jsp+Servlet+MVC
開發工具：Eclipse/Idea均可以匯入使用
資料庫：Mysql+Navicat
資料庫表：4張
適用：軟體工程、計算機科學與技術等JAVA課程的學習和實驗

PS:本系統基于web環境，在開發語言方面，由于Java的可移植性好，可在各個作業系統之間進行無障礙的轉換，具有多作業系統性，因而選擇Java作為本系統的開發語言，本系統的開發程序與一般的軟體開發類似，先進行系統的需求分析，再對系統進行總體設計，之后劃分模塊，最后再對每個單獨的模塊進行編碼與開發，而這一系列的設計程序都與一般的系統設計相同，并且Idea和Eclipse均可以使用
