SpreadSheet样式的数据操作具有很好的可用性,但在SpreadSheet结构中如何表示并操纵XML数据以及如何使用复制、粘贴、移动等简单操作表示复杂的XQuery查询是两个难点问题.提出一种基于XML模式的操作表示方法,将复杂的XQuery查询语句分解为XML模式上的粘贴节点、移动节点等操作,从而可以表示XQuery语言的核心语句FLOWR.在Spreadsheet结构中将XML模式显示为嵌套表格,用户在嵌套表格上的操作转换为XML模式上的操作.使用该方法可以构造多数据源的XQuery查询,并实现了概念验证的原型系统.与当前流行的XQuery查询构造工具相比较,原型系统更适合于无编程经验的最终用户构造XQuery查询.

Spreadsheet is intuitive for many non-technical users.But there are two difficulties in operating mnl data on spreadsheet.One is how to represent xml data in spreadsheet,and the other is how to express complex query with simple operations,such as copy,paste and move.A spreadsheet-like construct was proposed to represent XML data and to express complex query using a group of simple operations.XML Schema was represented as nested-table in spreadsheetlike construct and users'operations on spreadsheet were transformed into XQuery statements on xml schema.The spreadsheet-like construct was implemented in an information convergence system to query complex data distributed in heterogeneous data sources.Compared with popular XQuery constructing tools,spreadsheet is suitable for users with little or no experiences in programming to query complex data.
