保留太多信息会让分析师和工具淹没其中。但历史信息太少，将无法判断是否存在
趋势。这时，一个完善的历史表就能在你的分析中起到决定性的作用。保留正确的
情况信息，可以进行有意义的分析。让我们考虑一下历史表可以发挥作用的几种情
况：
员工动态
掌握谁在什么时候担任什么角色，以及员工在组织中的发展情况，可以为你的
组织如何发展和留住员工提供很多洞察力。
客户维护
就像留住员工一样，了解客户离开之前在你的组织中拥有哪些产品或持有哪些
资产，可以让你有机会改进你的产品，而不是只看当前的快照。
运营流程
当客户在试图满足他们的需求中陷入兜圈子的困境时，他们往往会感到沮丧（例
如，打电话给客服试图解决一个问题时，被转给多个客服）。如果组织对客户
在本企业的经历没有清晰的认识，就更难改进未来的流程。如果系统只掌握客
户的最新状态，就无法判断运营问题可能在哪里。可以通过查询运营数据，包
括电话和计算机系统日志，来深入了解客户在整个运营过程中的历程。
历史表可以让你存储数据点以备将来分析，并提供可能已经丢失的数据洞察力。

创建历史表时需要考虑的问题
如前所述，在存储所有的东西和支付高额的存储成本之间，或者在可能节省存储费
用和丢失有意义的数据之间，一直存在着矛盾。因此，本节将讨论在你建立自己的
历史表进行分析使用时需要注意的一些事项。
48.2.1
连接到实时数据的能力
历史表本身就可以为分析师提供有价值的数据洞察力。然而，将历史表与实时数据
结合起来，可以创建更强大、关联性更强的结果。
