So we extent its function by adding sqlquery expressions which contain sql. it gets results from queries by jdbc api and convert it into xml format. then it uses xquery complier to query in succession in order to integrate related databases
Xquery語言本身並不能實現該功能，所以我們對它進行擴展，增加嵌套sql語句的sqlquery表
達式，使用jdbc來查詢sql語句，而將產生的結果轉換為xml文檔，再使用xquery編譯器來實現查詢要求，
達到集成關系數據

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
基於這些準則，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演算法；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模擬（ bisimulation ）等問題進行了研究，提出了一種判定數據圖的bisimulation演算法；在xml數據查詢語言研究的基礎上，設計並實現了一種具有數據庫查詢特性的web查詢系統原型。
