Nowadays, the growing importance of modelling in software engineering is without a doubt reinforced by the blossoming of model-driven architecture (MDA). In this trend, MDA could be considered the most convenient approach to integrate the modelling process in data warehousing projects. On the other hand, decision-makers are usually unable to express their business needs in a concise way that allows getting a valid data warehouse (DW), mainly due to the lack of standard methodologies and tools devoted to supporting this situation. This fact might expand the gap between the business world and the IT world and causes troublesome difficulties to interpret and model DW requirements. Moreover, applying MDA for this kind of project requires using new tools to avoid this drawback. In this paper, we provide an MDA framework to design DW requirements and generate afterwards the multidimensional schema. The framework is based on UML profiles and presents to decision-makers a graphical tool for modelling their strategic visions in order to build the system-to-be. Besides, the proposal allows for dealing with data historization and metadata in the generated multidimensional model to perform properly the extract transform load process.

DAREF：用于对数据仓库需求建模并推导出多维模式的 MDA 框架

如今，模型驱动架构 (MDA) 的蓬勃发展无疑加强了建模在软件工程中日益增长的重要性。在这种趋势下，MDA 可以被认为是在数据仓库项目中集成建模过程的最方便的方法。另一方面，决策者通常无法以简洁的方式表达他们的业务需求，从而获得有效的数据仓库 (DW)，这主要是由于缺乏专门用于支持这种情况的标准方法和工具。这一事实可能会扩大业务世界和 IT 世界之间的差距，并导致难以解释和建模 DW 需求。此外，将 MDA 应用于此类项目需要使用新工具来避免此缺点。在本文中，我们提供了一个 MDA 框架来设计 DW 需求并随后生成多维模式。该框架基于 UML 配置文件，并为决策者提供了一个图形工具，用于对他们的战略愿景进行建模，以构建未来系统。此外，该提议允许处理生成的多维模型中的数据历史化和元数据，以正确执行提取转换加载过程。
