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。
A group of database operations combined into a logical unit of work that is either wholly committed or rolled back 对星型架构的一种扩展,即,由多个表定义一个或多个维度。
Provides a conceptual overview of cubes in analysis services , and an example of a cube that uses a star schema 提供对analysis services中多维数据集的概念性概述,并提供使用星型架构的多维数据集示例。
For example , if you are loading data into a star schema , you can build a separate package to populate each dimension and the fact table 例如,如果将数据加载到星型架构中,则可以生成一个单独的包来填充每个维度和事实数据表。
Many - to - many dimension relationships expand the dimensional model beyond the classic star schema , and support complex analytics even when dimensions are not directly related to a fact table . for more information , see 多对多维度关系扩展了维度模型,使其超越了传统的星型架构,并且即使在维度没有直接与事实数据表相关时也可以支持复杂的分析。
