接下来,数据架构师将这些原子域与物理模型中的物理列关联起来。
The data architect can then associate these atomic domains to physical columns in the physical data model.
注意,这个原子域被定义为 DOUBLE,而数据库列(由反向工程决定)的数据类型为 BIGINT。
Note that this atomic domain is defined as DOUBLE, while the data type for the database column (determined using reverse engineering) is a BIGINT.
原子信息在关系型列中所占据的空间要比在冗长 XML 表示中所占据的空间要小
The atom information takes less space in relational columns than in their verbose XML representation.
