Gather business requirements and data realities
Gather business requirements and data realities
汇聚业务需求与数据现实
Before launching a dimensional modeling effort, the team needs to understand the needs of the business, as well as the realities of the underlying source data. You uncover the requirements via sessions with business representatives to understand their objectives based on key performance indicators, compelling business issues, decision-making processes, and supporting analytic needs. At the same time, data realities are uncovered by meeting with source system experts and doing high-level data profiling to assess data feasibilities.
在启动维度建模工作之前，团队需要理解业务的需求，以及底层源数据的现实情况。需求通过与业务代表的座谈会来挖掘：基于关键绩效指标（KPI）、紧迫的业务问题、决策流程和支撑性分析需求，理解他们的目标。与此同时，数据现实则通过与源系统专家的交流以及高层次的数据剖析（data profiling）来揭示，以评估数据的可行性。
