Managing Data Catalog Tables and Databases - AWS Lake Formation

Managing Data Catalog Tables and Databases

AWS Lake Formation uses the AWS Glue Data Catalog to store metadata about data lakes, data sources, transforms, and targets. Metadata about data sources and targets is in the form of databases and tables. Tables store information about the underlying data, including schema information, partition information, and data location. Databases are collections of tables. The Data Catalog also contains resource links, which are links to shared databases and tables in external accounts, and are used for cross-account access to data in the data lake.

Each AWS account has one Data Catalog per AWS Region.
