一、項(xiàng)目簡介
現(xiàn)代經(jīng)濟(jì)快節(jié)奏發(fā)展以及不斷完善升級(jí)的信息化技術(shù),讓傳統(tǒng)數(shù)據(jù)信息的管理升級(jí)為軟件存儲(chǔ),歸納,集中處理數(shù)據(jù)信息的管理方式。本智慧養(yǎng)老平臺(tái)就是在這樣的大環(huán)境下誕生,其可以幫助管理者在短時(shí)間內(nèi)處理完畢龐大的數(shù)據(jù)信息,使用這種軟件工具可以幫助管理人員提高事務(wù)處理效率,達(dá)到事半功倍的效果。此智慧養(yǎng)老平臺(tái)利用當(dāng)下成熟完善的SSM框架,使用跨平臺(tái)的可開發(fā)大型商業(yè)網(wǎng)站的Java語言,以及最受歡迎的RDBMS應(yīng)用軟件之一的Mysql數(shù)據(jù)庫進(jìn)行程序開發(fā)。實(shí)現(xiàn)了老人基礎(chǔ)數(shù)據(jù)的管理,家人管理,機(jī)構(gòu)社區(qū)人員管理,服務(wù)管理,留言管理,公告信息的發(fā)布等功能。智慧養(yǎng)老平臺(tái)的開發(fā)根據(jù)操作人員需要設(shè)計(jì)的界面簡潔美觀,在功能模塊布局上跟同類型網(wǎng)站保持一致,程序在實(shí)現(xiàn)基本要求功能時(shí),也為數(shù)據(jù)信息面臨的安全問題提供了一些實(shí)用的解決方案??梢哉f該程序在幫助管理者高效率地處理工作事務(wù)的同時(shí),也實(shí)現(xiàn)了數(shù)據(jù)信息的整體化,規(guī)范化與自動(dòng)化。
