snowflake schema meaning in Chinese
雪花架构
雪花型架构
Examples
- Use of a star or snowflake schema to organize the data within the database
使用星型架构或雪花架构来组织数据库内的数据。 - When you define a dimension based on a snowflake schema , which is where dimension attributes are derived from multiple related tables , an attribute relationship is automatically defined as follows
当您基于雪花型架构（在该架构中，维度属性派生自多个相关的表）定义维度时，会按如下方式自动定义属性关系： - For the inquiring convenience , comprehensive service and the following data digging , all the tables of system are grouping , and re - edited into “ star schema ” or “ snowflake schema ” . hibernate is an object - relation mapping software which is more and more popular
在本系统中为了方便查询,给用户提供更全面的服务以及下一步要开展数据挖掘等工作,将所有数据表分组,重新设计表结构实现了“雪花型”或“星型”多维数据模型。 - In the process of building the multidimensional data model , we made some mends on the time dimension , adapted the time model based on competition , and this model provided enough information for the later analysis based on time . and contempary , this paper used a new schema called star cluster schema as the basic structure of the multidimensional data model . the cluster schema is the joint of star schema and snowflake schema , it inherits their merits , and mends their disadvantages
在具体的建模过程中，对时间维作了一定的修正，提出了一种基于竞争机制的时间维模型，为基于时间的分析提供了更加充分的信息；同时本文也对常用的多维数据模型的结构作了改进，采用了一种称作为星族模式的结构，这种结构结合了星型模式和雪片模式的优点，同时又对各自的缺点进行了修正，并在实际中得到了很好的应用。
