如何在数据仓库model中单独放置一张表?

[英]How to fit a separate table in data warehouse model?

I have a table named AWARENESS_MEETINGS with name and date of the meeting as an attributes, it's not related to any other table in the database.我有一个名为 AWARENESS_MEETINGS 的表,其名称和会议日期作为属性,它与数据库中的任何其他表无关。 I am designing a data warehouse model, I can't fit it into the model its only related to the date dimension, and I can't determine if it's a fact or dimension table, the only business question related to the table is the count of the AWARENESS_MEETINGS by time.我正在设计一个数据仓库 model,我无法将它放入 model 它只与日期维度相关,我无法确定它是事实表还是维度表,与表相关的唯一业务问题是计数AWARENESS_MEETINGS 的时间。
