  1. 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核心法提出了兩方面擴充;給出了計算數據圖中規表達的演算法;對半結構數據的一階邏輯描述、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數據研究的基礎上,設計並實現了一種具有數據庫特性的web系統原型。
  2. One of the earliest activities of the query working group was to draw up a formal statement of requirements for an xml query language

    Query工作組的早期活動之一就是起草xml需求的聲明。
  3. In the research of xml query language, we consider the requirement of two categories ( for data - centric and for document - centric ) of xml applications and point oat that the basic operations in xml - quey are pattem matching, selection and filtering, and result reconstfuction. the path expression and the flwr expression in xquery are typical structurs tha are comprised of these operations

    在對xml的研究中,從以文檔為中心和以數據為中心這兩類xml應用需求的分析出發,指出xml的基本操作是模匹配、選擇過濾和結果構造, xquery中路徑(包括簡單路徑和規路徑)表達和flwr表達是進行這些操作的典型結構。
  4. Topics include : relational databases, sql ( structured query language ) ; types, relations, relational algebra, integrity, view ; functional dependency theory, normalization, semantic modeling, entity - relationship modeling, conceptual database design ; concurrency control, security ; database and web connectivity, xml

    主題包括:關聯資料庫、 sql (結構) ;資料類型、關聯、關聯代數、完整性、景觀表;功能依附理論、規化、義塑模、實體關聯塑模、概念性資料庫設計;同時操作控制、安全;資料庫與網頁連結、 xml (可擴展標示) 。
  5. The expressive power of xquery is comparable to the criterion of relational completeness " defined for database query languages, though no such formal standard has been defined for an xml data model

    Xquery的表達能力可以與為數據庫定義的「關系完整性」標準相比,雖然還沒有為xml數據模型定義這樣的標準。
