    • The subject invention pertains to systems and methods that facilitate generation of a database to support a multidimensional model. A database schema is generated in a top-down fashion. In particular, multidimensional structures and attributes such as cubes and dimensions can be defined. From such definition, a proposed database schema can be produced. This schema can subsequently be modified prior to or after populating the database. For example, a table or column could be added. Thereafter, the cubes and dimensions could be altered and a modified schema generated that preserves changes made to the schema. Accordingly, the subject systems and methods disclose an iterative approach that supports both top-down and bottom-up multidimensional database design.
    • 本发明涉及促进数据库生成以支持多维模型的系统和方法。 以自顶向下的方式生成数据库模式。 特别地,可以定义多维结构和属性,例如立方体和维度。 从这样的定义可以产生一个提出的数据库模式。 随后可以在填充数据库之前或之后修改此模式。 例如,可以添加表或列。 此后,可以修改立方体和维度,并生成修改后的模式,以保留对模式所做的更改。 因此,主题系统和方法公开了支持自上而下和自下而上的多维数据库设计的迭代方法。
