基于类型图模型的信息集成
Information Integration using the Typed Graph Model
摘要：
40多年来，模式和数据集成一直是一个挑战。虽然数据仓库技术是一个相当成功的故事，但仍然缺乏信息集成方法，特别是当数据源基于不同的数据模型或没有模式时。企业信息集成需要处理异构的数据源，需要最新的高质量信息为分析和决策提供可靠的依据。本文提出了虚拟集成使用类型化图模型来支持模式中介。集成过程首先将每个源的结构转换为类型化图模式，然后将其与中介模式进行匹配。映射规则定义模式之间的转换以协调语义。专家可以直观地验证映射。它提供了指标和规则来实现一致的模式映射，从而实现高数据完整性和质量。
英文摘要：
Schema and data integration have been a challenge for more than 40 years. While data warehouse technologies are quite a success story, there is still a lack of information integration methods, especially if the data sources are based on different data models or do not have a schema. Enterprise Information Integration has to deal with heterogeneous data sources and requires up-to-date high-quality information to provide a reliable basis for analysis and decision making. The paper proposes virtual integration using the Typed Graph Model to support schema mediation. The integration process first converts the structure of each source into a typed graph schema, which is then matched to the mediated schema. Mapping rules define transformations between the schemata to reconcile semantics. The mapping can be visually validated by experts. It provides indicators and rules to achieve a consistent schema mapping, which leads to high data integrity and quality.
