图形数据缩小了人类和计算机看待世界的方式之间的差距。计算机依靠静态的数据行和列，而人们通过人际关系来导航和推理生活。这个实用指南演示了图形数据如何将这两种方法结合在一起。通过使用来自图论、数据库模式、分布式系统和数据分析的概念，您将到达一个独特的交集，即图思维。
本书作者Denise Koessler Gosnell和Matthias Broecheler向数据工程师、数据科学家和数据分析师展示了如何用图表数据库解决复杂问题。您将探索使用图技术构建的模板，以及演示团队如何在应用程序中考虑图数据的示例。

丹尼斯·K.戈斯内尔，Denise Koessler Gosnell博士是DataStax的首席数据官。她建立了数十个与图论、图算法和图数据应用相关的流程并申请了专利。
