摘要：
本文研究了决策支持系统中的数据仓库建模问题。我们提供了一个面向对象的数据仓库模型，允许数据仓库描述为相关的，复杂的和临时的数据的中央存储库。该模型集成了仓库对象、环境和仓库类三个概念。每个仓库对象由一个当前状态、几个过去的状态（模拟其详细的演变）和几个存档状态（在摘要形式中模拟其演变）组成。环境概念定义了数据仓库模式中具有显著粒度（属性、类、图）的时态部分。最后，我们提供了五个功能，旨在定义数据仓库的结构和两个功能，允许仓库类继承层次结构的组织。
英文摘要：
In this paper, we study the data warehouse modelling used in decision support systems. We provide an object-oriented data warehouse model allowing data warehouse description as a central repository of relevant, complex and temporal data. Our model integrates three concepts such as warehouse object, environment and warehouse class. Each warehouse object is composed of one current state, several past states (modelling its detailed evolutions) and several archive states (modelling its evolutions within a summarised form). The environment concept defines temporal parts in the data warehouse schema with significant granularities (attribute, class, graph). Finally, we provide five functions aiming at defining the data warehouse structures and two functions allowing the warehouse class inheritance hierarchy organisation.
