中文简介:
考虑了一种集成信息的原始方法。在这种方法的框架下,基于高级XML数据模型的代数模型,建立了一个可扩展的规范模型。我们认为规范模型是创建中介体的中间模型,并且该模型已经通过抽象机器符号(abstract machine notation,AMN)形式化。对于每个源模型,我们通过AMN将其形式化,并创建一个可逆映射到规范模型的扩展中。在此基础上,利用B技术证明了源模型的AMN语义是对扩展规范模型AMN语义的一种改进。由此证明了映射的正确性和使用扩展规范模型表示源模型模式的能力。最后,为了说明我们的方法,创建了从关系数据模型到规范模型的映射。
课程简介: An original approach to integrate information is considered. In the frame of this approach an extensible canonical model is created which is based on the algebraic model of an advanced XML data model. We consider the canonical model as an intermediate model for creating our mediator and this model has been formalized by means of the Abstract Machine Notation (AMN). For each source model we formalize it by means of the AMN and create a reversible mapping into an extension of the canonical model. After this B-technology is used to prove that the AMN semantics of the source model represents a refinement of the AMN semantics of the extended canonical model. Hereby the correctness of mapping and the ability to use extended canonical model for representation of schemas of the source model are proved. Finally, in order to illustrate our approach a mapping from relational data model to canonical model has been created.
