隨著時代的發展，醫療設備愈來愈完善，醫院也變成人們生活中必不可少的場所。如今，已經2021年了，雖然醫院的數量和設備愈加完善，但是老齡人口也越來越多。在如此大的人口壓力下，醫院住院就變成了一個問題。目前預約住院看病住院在國內已經是一種習慣了，在歐美國家，除了急診，患者看病一般都采取預約住院，而且國外的網上預約技術已經較為成熟。隨著互聯網網絡的迅猛發展，網絡用戶已經越來越多，網上預約住院也應該成為醫院住院的主流方式了。網上預約住院系統是一種基于互聯網的新型住院系統。使用預約住院系統，用戶就可以在網上預約醫院的專家、專科號。它能更好的改善就醫環境，簡化就醫環節，節約就醫時間，真正體現了以病人為中心，切從方便患者出發，符合當今醫院人性化溫馨服務的理念。本醫院住院管理系統采用的數據庫是Mysql，使用SSM框架開發。在設計過程中，充分保證了系統代碼的良好可讀性、實用性、易擴展性、通用性、便于后期維護、操作方便以及頁面簡潔等特點。
