desiderate

We first present a number of desiderata for an xml - based query language , and based on this criterion , we introduce the syntax of a simple core ian - guage for semistructured data and then describe four extensions that have resulted in working prototypes . second , we present the algorithm for computing the result of a regular expression on data graph with cycles , the first - order interpretation of querying language for semistructured data , and explore structural recursion and bisimulation in semistructured data and propose an efficient and systematic way to computing a bisimulation between the two graphs . we also proposed and implemented a web querying system with database features 基于這些準則,對一個簡單的半結構數據查詢核心語言的語法提出了兩方面擴充;給出了計算數據圖中正規表達式的算法;對半結構數據查詢語言的一階邏輯描述、結構遞歸和數據圖的雙態仿真( bisimulation )等問題進行了研究,提出了一種判定數據圖的bisimulation算法;在xml數據查詢語言研究的基礎上,設計并實現了一種具有數據庫查詢特性的web查詢系統原型。
