摘  要
隨著計算機技術的發展，越來越多的行業實現了管理的信息化和自動化。教育行業也不例外。為了滿足現代教學的需求，進一步加強老師和學生的交流，同時改變過去傳統的作業批改方式, 設計了基于B/S 模式的在線作業批改系統。系統包括教師模塊和短消息模塊，教師模塊主要是實現教師布置作業、批改作業、發布成績等。短信息主要是實現信息的發送、編寫、查看。論文詳細闡述了系統的開發背景、研究意義，開發環境以及系統的需求分析，詳細說明了數據庫的設計，以及系統各功能的實現。
在線作業批改系統有著很好的應用前景，用來代替傳統的作業批改方式，實現在線作業批改方式的網絡化管理。隨著計算機技術和網絡技術的發展，它的功能將會得到不斷的發展和完善。

Abstract
As computer technique develops, more and more trades achieve information retrieva l and automation for management, so as to education. Meeting modern teaching's demands ,online homework correcting system is designed on account of B/S mode, which can improve interchange between students and teachers, changing old traditional ways of homework correcting. The system includes teacher part and messenger part. Teacher part mainly achieves teachers ‘assigning homework, correcting homework and score reporting, while message part mainly achieves message sending, composing and reading. The system’s designing background, studying significance, developing environment and needs analysis are stated with details, so as to data room designing and how parts of the system achieve their function. 
 Online homework correcting system now holds good application prospects, taking place of traditional ways of homework correcting and bring about net management for online homework correcting. As computer and network technique develop, its function will get continual improvement and development.
Keywords: B/S; homework correcting; message; database; .NET
