Projects | Name |
Tables | Name, Description, Created date, Last modified date, Default table expiration, Data location, Labels, Type (Standard, External, Snapshot, Model), Partitioned on field, Clustered by columns for standard and snapshot tables, Partition type (range or time) requires partition filter - Range (Start, end, interval) Time (Partition type (hour, day, month, year), expiration) |
Columns | Name, Description, Data Type, Is Nullable, Column size |
View | Name, description, created date, default table expiration, last modified date, data location, default collation, labels, view SQL, clustered by columns for materialized |
Relationship between objects

If the metadata presentation for this data source has been customized with the help of the data.world Solutions team, you may see other resource pages and relationships.
Resource page | Relationship |
---|---|
Datasets | Tables, Views |
Projects | Dataset |
Tables | Column, Labels |
Columns | Table, View |
Views | Column |
Label Value | Table, View, Project, Dataset |
