Viewing data access patterns

In NoSQL Workbench, facets represent an application's different data access patterns for Amazon DynamoDB. Facets give you a way to view a subset of the data in a table, without having to see records that don't meet the constraints of the facet. Facets are considered a visual data modeling tool, and don't exist as a usable construct in DynamoDB, as they are purely an aid to modeling of access patterns.
