資源簡(jiǎn)介
學(xué)生平時(shí)考勤都是由老師在教室按照班級(jí)花名冊(cè)逐個(gè)點(diǎn)名，教務(wù)部門(mén)要想了解學(xué)生準(zhǔn)確的出勤情況，往往需要各任課老師或班主任將出勤情況進(jìn)行統(tǒng)計(jì)匯總，這樣下來(lái)話費(fèi)的時(shí)間較長(zhǎng)。同時(shí)由于班級(jí)多、人數(shù)多、人流量大等特點(diǎn)，學(xué)生出勤記錄數(shù)據(jù)檢索也比較困難，而且紙質(zhì)點(diǎn)名簿的保存也很不方便。為了方便學(xué)生管理， 節(jié)約資源，提高學(xué)生管理工作效率，編寫(xiě)了本學(xué)生考勤管理系統(tǒng)。使用jsp+javabean+servlet編寫(xiě)具體可用的系統(tǒng)。
