Overview
Data lakes are centralized repositories that store vast amounts of raw data, which can be structured, semistructured, or unstructured data. With such massive amounts of data stored in a single repository, categorization is needed to organize these assets. This is where data catalogs come in. A data catalog helps organizations manage their data by using metadata to create an inventory of all enterprise data within a data lake. This makes it easier for data analysts and business users to collect, organize, and access data. Successful data catalog implementations enable data discovery, strengthens security and data access, and supports compliance and data governance initiatives within an organization.
