Diagram depicting a customer's AWS account and an AWS managed AWS account. In the customer account, there is a region box. In the region, there is an Amazon Athena workgroup taking 3 steps. In the first step, the workgroup accesses metadata from the AWS Glue Data Catalog named default. The catalog has a dotted line to an AWS Glue table called amazon_reviews_parquet, which has the attributes and S3 bucket location. The second step from the workgroup queries data from the S3 bucket. The S3 bucket is in the AWS managed AWS account. The bucket is for the Amazon Customer Reviews dataset. In the third step, the workgroup stores the query results in the Amazon S3 bucket in the customer AWS account. The query results can then be read by users with read access to the Athena workgroup.
