迄今为止，在我的职业生涯中我经历了传统数据分析周期中的所有角色──从一个
痛苦忍受等待为我建立报表过程的用户，到学习如何为自己建立数据分析的人，再
到在数据库中整理数据集的人，最后到培训他人进行数据可视化和数据准备技能的
人。
潜在的数据准备者（“准数据准备者”）和熟练的数据准备者之间还有很大的差距。
学习如何使用自助式数据准备工具，以及了解为什么需要这些工具，是一项重要的
工作，也是很值得的。
Prep Builder
会让我多年来积累的知识更容易让你学习并直接
投入具体应用。

节中，你将学习如何利用这些工具来解决目前在你的组织中存在障碍的任务。在练
习中我们将介绍常用的技术，以解决这些问题从而减少工作中的压力。随着时间的
推移，你将学会制定自己的策略，以完全按照你自己的要求准备数据，无论数据来
自文件、数据库、调查表、数据转换表、凌乱的数据还是杂乱的文本字段。不存在
某种简单的方法来让你遵照执行，但只需通过实践，你很快就能处理这些难题。
