> 中文摘要: 提出了一种称为Macor的模型来表示嵌套模式之间的映射关系.Macor将一个完整的模式映射表示成众多简单的原子映射,并用关联关系将它们连接在一起.进一步根据XQuery分析了Macor的表达能力,并处理了Macor的实现问题.初步的实验结果表明,通过Macor模型,一个复杂的映射不仅可以按照增量方式逐步建立,还能将修改和维护限制在局部的原子映射和关联关系上.

Abstract:This paper proposes a model called mapping & correlation (Macor) to represent nested schema mappings. With Macor, a full mapping is modeled as a number of simple atomic ones that are correlated with correlations. The expressive power of Macor by a fragment of XQuery called CoXQ is studied and the issues in implementing Macor are addressed. Preliminary experimental results show that with Macor a full mapping can be modeled incrementally in a piecemeal fashion, and in refining or maintaining the mappings, Macor makes it possible to locate modifications to few atomic mappings and correlations, and reuse other parts of the full mapping.
