和从前一样，有三种方法可生成数据库分区映射：平均法，通过分布数组指定权重(使用distfile)，以及用户指定(使用targetmap)。

Just as before, there are three ways to generate a database partition map: uniform, weighted through a distribution array (using distfile), and user specified (using targetmap).

在这两种方法中，用户数量的比例是相似的——只是组的数量和权重有所不同。

The proportion of the user population is similar in both approaches — only the amount and the weight of the segments are different.

论文列出了确定指标权重的具体操作方法和步骤。

The dissertation also lists specific operation methods and approaches to confirm the weight of each indicator.
