The document discusses using a data lake to integrate learning and performance data from various sources to gain insights. A data lake stores all enterprise data in its raw format and can include structured, semi-structured, and unstructured data. Learning and performance data is increasingly stored across different systems. The data is extracted and joined in the data lake using common fields. Tools are needed for data scientists and citizen data scientists to analyze the data to understand correlations and improve business goals like partner program management and sales opportunities. Freely available tools for working with data lakes are recommended.
