在一个面向对象的转口贸易中对历史和档案资料的调制和处理
Modélisation et manipulation de données historisées et archivées dans un entrepôt orienté objet
摘要：
本文讨论了面向时态和归档对象的数据仓库建模和查询。在第一步中，我们定义了一个数据模型，将仓库描述为从一个信息源中提取的复杂和时态数据的中央存储库。该模型基于仓库对象和环境的概念。仓库对象由一个当前状态、几个过去状态（建模值更改）和几个存档状态（总结一些值更改）组成。环境根据相关粒度（属性、类或图）定义仓库模式中的时态部分。在第二步中，我们提供专用于数据仓库的查询代数。该代数以公共对象代数为基础，集成了时态算子和查询对象状态的算子。另一个重要的贡献涉及专门的运营商，允许用户转换仓库对象的时间序列，以及运营商促进分析处理。
英文摘要：
This paper deals with temporal and archive object-oriented data warehouse modelling and querying. In a first step, we define a data model describing warehouses as central repositories of complex and temporal data extracted from one information source. The model is based on the concepts of warehouse object and environment. A warehouse object is composed of one current state, several past states (modelling value changes) and several archive states (summarising some value changes). An environment defines temporal parts in a warehouse schema according to a relevant granularity (attribute, class or graph). In a second step, we provide a query algebra dedicated to data warehouses. This algebra, which is based on common object algebras, integrates temporal operators and operators for querying object states. An other important contribution concerns dedicated operators allowing users to transform warehouse objects in temporal series as well as operators facilitating analytical treatments.
