CBDB中记载人数的时代分布

Population Distribution among Dynasties in CBDB


CBDB数据包含了从秦前到中华人民共和国上下两千年的历史，目前所记载人数约有417,000人。
本图展示数据库中所记载人数的时代分布，并用颜色区分朝代。
值得一提的是，数据库中采用“指数年”来描述人与年份的对应关系，它指人在顶峰时期的年份，常用60岁时的年份替代。这一指标既满足了人与年份的对应关系，也暗合了人的能动性。

CBDB contained biographical information about approximately 417,000 individuals by April 2017,ranging from Qin Dynasty to People's Republic of China.
The graph shows population distribution among dynasties distinguished with color.
It is worth mentioning that "index year" is assigned to match people and years, indicating the peak of people's life, which is often defined as the age 60. "Index year" satisfies the correspondence between people and years, as well as confirms to motiity in people.


    维度多

    Multi-Dimensional


CBDB从多种维度记录人物信息，除人物的姓名、生卒年等基本信息外，还包括了相关地址、任官、亲属、社会关系、著述等信息。
本图展示数据库中主要的八张表，表之间通过人物id相关联。此外，还有一些存储更多的信息的表，如使用表”任官地“对”任官“进行详细说明。
