A join of two datasets can result in fewer rows in the joined result, while a union of two datasets always results in an increased number of rows in the result.

Study Notes
Data Transformation and Sources
- Data transformation and blending occur in the Data Catalog.
- Refreshing data in the Prism data source requires re-importing base datasets or tables and republishing the data source.
User Access and Dataset Creation
- Not everyone with access to the Data Catalog can create datasets.
- The domain “Prism Dataset: Manage Data Source” provides access to view or edit Prism data source security.
Dataset Publishing and Schema
- Publishing a dataset in Workday creates a data source for reporting.
- Including instance field types in custom reports is important for actionability when reporting on published Prism data sources.
- If new fields are added to a file after the first import, the base dataset must be manually re-saved to accept the new schema.
Data Handling Modes
- Dataset Update Mode: Append does not insert unique rows, but rather allows for repeated entries.
- Unique rows can only be inserted to a table through the Upsert operation.
Field Management and Transformations
- Not all types of transformations can be added to base datasets or tables.
- Managing fields cannot change the output type of a field for needed downstream transformations.
Calculated Fields and Runtime Values
- Changing a field name used in a downstream Prism calculated field will result in an error.
- Prism calculated fields' values are determined at the time of publishing, not during report runtime.
Joins and Dataset Operations
- Use a Left Outer Join to include all rows from the primary pipeline, regardless of matches with the imported pipeline.
- A join can result in fewer rows, while a union usually increases the number of rows in results.
Matching Fields Criteria
- When matching fields in a join configuration, they must be of the same type.
- Selecting the If Any option in a basic filter is akin to using the OR operator.
Data Aggregation and Filters
- The Group By stage returns only aggregated data, not detail data.
- Filter condition changes do not require edits to all downstream transformation stages.
Field Additions and Dataset Types
- Adding fields to a dataset necessitates editing downstream Join, Union, or Manage Fields stages to reflect the additional fields.
- Prism data sources can be used in various report types, not exclusively in Matrix report types.
Security Configurations and Changes
- After editing security configurations of a Prism data source post-publication, it is necessary to republish the data source for changes to take effect.
