设计数据库时必须将维度模式星型架构与IWA相结合，必须定义表格并将它们载入IWA中，以充分利用IWA的性能。
A database must be designed using a dimensional model star schema to work with IWA, and the tables must be defined and loaded into IWA to take advantage of its performance.
您还可以修改一些规范，比如图表的范围和类型(条形图或线形图，层叠图或聚类图)、颜色和模式选项、细分维度和工具提示。
You will be able to modify some of the specifications such as the range and type of chart (bar or line, stacked or clustered), color and pattern choices, breakdown dimension and tooltips.
数据库设计师长期使用术语“星型模式”来描述维度模型，因为结果结构看上去像一个星星。
Database designers have long used the term "star schema" to describe dimensional models because the resulting structure looks like a star.
