【摘要】對目前基于Web的醫院信息系統（HIS）在數據檢索時存在等待時間過長的問題進行了分析，提出了一種基于AJAX的Web應用模型來減少服務器響應時間；同時研究了檢索優化的代價模型，采用一種基于存儲過程的分頁算法對HIS的數據檢索模型進行了優化。對比實驗表明，優化后的HIS數據檢索明顯縮短了等待時間，提高了檢索效率，可以使用戶獲得更好的檢索效果。

Abstract: The problems that retrieving data cost a long waiting time, which appeared in the current Web-based Hospital Information System (HIS), was analyzing in this paper and a Web application model based on AJAX was put forward to reduce the response time of the server. A cost model to optimize the retrieval was also discussed. Thereafter, a paging algorithm based on storing process was adopted for the optimization. The contrasting experiment shows that the waiting time of the proposed method was clearly reduced and the efficiency was improved significantly, which gave users a better retrieval experience.
Keywords: ajax; retrieval optimization; data paging; storage process; web application
