1.系統功能分析
1.1系統信息要求
1）學生基本信息如下：
學號、姓名、宿舍號、性別、年齡；
學號爲標準格式1234567890十位，其中前兩位代表學生入學年份，3-4位代表學生所在學院，5-6位代表學生所學專業、7-8位代表學生所在班級，9-10位代表學生在班級中的序號。
姓名最多爲4個漢字；
性別爲“男”或“女”；
年齡爲2位正整數
2）課程信息如下：
課程號、課程類別、課程所在學期、課程名稱、學分；
課程號爲標準課號。例如B08010100；
課程類別爲：選修/必修
所在學期用阿拉伯數字1-8代表
課程名稱爲專業爲2014版人才培養計劃中的課程名稱
3）學生成績信息如下：
學號、課程號、課程成績、是否重修
學號爲學生信息中的主關鍵字，可以唯一識別學生。課程號爲課程信息的主關鍵字，可以唯一識別課程。是否重修用於判斷課程成績是否是第一次考試取得。
4）綜合信息
學號、姓名、獲獎類別、獲獎時間、懲處類別、懲處時間、所獲學分、獎勵分值、懲罰分值。獎懲分起始值均爲0分。
1.2功能分析
1.2.1錄入部分
1）能實現學生信息的錄入、修改並保存；
2）能實現課程信息的錄入、修改並保存；
3）能分學期錄入品行表現成績（輔導員、班主任、班級評議）、修改並保存
4）能實現課程成績的錄入，並且在實現某課程成績錄入時，能夠自動按學號排好順序，並提示“某學號、某同學 某門功課成級”，例如“1508100201 丁兆元 C語言程序設計A成績”。
5）能錄入學生的各種獎懲信息
1.2.2修改部分
1）能對錄入的課程成績進行修改，例如成績錄錯、重考、重修原因引起的成績更改等。
2）能對個人信息進行修改
3）能對課程信息進行修改
4）能對學生獎懲信息進行修改
1.2.3統計分析部分
1）能對某門功課各分數段成績進行統計
2）能分學期對學生業務課程平均分按分數段進行統計
3）能統計任意一名同學每門功課的班級排名以及業務課成績總體排名
4）能以宿舍爲單位進行成績統計分析
5）能以掛科次數爲依據分學期對比分析
6）能以業務課班級排名爲依據分學期對比分析（前進或退步情況）
1.2.4排序部分
1）分學期按業務課程成績對學生由高到低排序，並顯示業務成績平均分。
2）分學期按不及格門次對學生由高到低排序，並顯示不及格門次。
3）分學期按不及格學生數對課程進行由高到低排序，並顯示課程名及不及格學生數。
4）能分學期以宿舍爲單位按成績由高到低進行排序，並顯示宿舍平均成績。
5）能隨時根據獎勵對學生進行由高到低排序並輸出信息。
6）能隨時根據懲罰情況對學生由低到高排序並輸出信息。
1.2.5獎學金自動評定
能根據學校獎學金評選辦法，分學期進行獎學金評定並顯示，並能夠將評選結果自動追加到學生的獎懲信息庫。
1.2.6數據的導入導出
基礎數據一次錄入永久存放，在需要時導入內存變量，如有修改重新導入文件，使永久保存的數據與臨時使用的數據保持一致性。
1.3獎學金評選標準
1.3.1獎學金評選資格。有下列情形之一者，不能獲得獎學金：
1）品行表現測評名次在班級70％以後者；
2）必修課或選修課有不及格者；
3）未達到《大學生體育鍛煉合格標準》者；
4）受警告以上處分者，半年或察看期內不得參加獎學金評選；
5）品行表現具有不宜獲得獎學金的其他情形者。
1.3.2綜合獎學金的評選
該獎項用於獎勵品學兼優、素質全面發展的優秀學生。
（1）獎勵等級、金額、比例爲：
特等獎2000元／人•年 3‰
一等獎1200元／人•年 3％
二等獎700元／人•年7％
三等獎400元/人•年15％
（2） 一、二、三等獎學金
以班級爲單位，根據綜合測評名次排列，列前35％名次者可參評獎學金。一、二、三等獎學金不全部評選的班級，可按學生數的3％、7％、15％的比例，只評選其中的一個等級。
1.4綜合成績計算標準
獎勵分值計算辦法，起始分值爲0分。
（1）獎學金計分：
獲得單項獎學金+1，三等獎學金+2，二等獎學金+3，一等獎學金+4，特等獎學金+5，校長獎學金+6。
（2）榮譽積分：
校級各種優秀個人+3，省級各種個人優秀+6，國家級各種優秀+12；
（3）學科競賽：
省級以上學科競賽成功參賽獎+1，省級三等獎+4、省二等獎+5、生一等獎+6，國家級三等獎+6、國家級二等獎+9、國家級一等獎+12，校級三等獎+1.校級二等獎+2，校級一等獎+3分。
（4）懲罰分值計算辦法，起始分值爲0分。
學院通報批評-1，校級警告-2，嚴重警告-3，記過-4，記大過-5，開除學籍留校察看-6。
