When working with complicated data, data discovery is­­­ a critical step in the data preparation process. Completing data discovery step allows you to gain some initial understanding as to what is actually in the dataset and how it can be leveraged for analytics and valuable business insights.

The process of data discovery can be difficult when working with various datasets that are not well structured to begin with or that are too large to use with common tools such as excel. For an analyst working with a new or third-party dataset, the faster they’re able to perform the process of data discovery, the faster they’re able to show value from their work.
