Depending on how your dimensions are created, there are many ways to get to this new dimension, e.g. create it in the same TI process as the original dimension.
根据您创建维度的方式，有多种方式可以达到这个新维度，例如，使用与创建原维度所用的同一TI流程创建该维度。
The attributes of a dimension or facts object are columns or column expressions on the set of joined tables that comprise the dimension or facts object.

Although each dimension is composed of several ele-ments, most studies center on one element within each dimension.
尽管每一个维度都由几个因素构成，但是大多数的研究是关注在每一个维度中的某一个因素。
All users who do not belong to a role with explicit authorization on the dimension are members of the default role, and they are able to access the dimension according to the default policy.
只要用户不属于对维度具有显式授权的角色，它就属于默认角色的成员，可以根据默认策略访问该维度。
One of the steps of processing the attributes of each dimension is identifying which attributes from each dimension are to be selected as columns in the SQL statement.
处理每个维的属性的步骤之一是，识别出在sql语句中选择哪些维属性作为列。
In a star join plan, the database server pushes down keys from a dimension table to filter the fact table at the same time as it builds the hash table on the dimension table.
星型连接计划中，数据库服务器在维度表中构建散列表的同时从维度表中下推键来过滤事实表。
For example, in the relationship expression between the time dimension and the fake fact, a filter can be applied to reduce the records from the time dimension to just a few days.
例如，在时间维度和伪事实的关系表达式中，可以使用过滤来将时间维度缩小到几天之内。
