The following default model conversions are provided at a repository level and will automatically be available for use in any subsidiary version of the repository.

Star Schema Group

Model conversions for transitioning from Physical category to Star schema category.

Model conversion

Description

3NF to Star Schema

Converts the 3rd Normal Form system model into a Star Schema with Facts, Dimensions, Surrogate keys and data lineage. By default, relies on the model being in a category (e.g. Physical) that contains an entity type of "Fact source" where the user will assign this entity type to entities that represent a "Fact" entity, usually the entities with the largest row count or several measuring attributes.

  • Recommended Usage - Transitioning from "Physical" category to "Star schema" category.
  • Where to From here - Apply model conversion "Generate Load and Stage tables".

3NF to Star Schema Views

Converts 3rd Normal Form tables into Dimensional star schema implemented via database views, often used for presentation layer virtualization. Similar to the purpose and behavior of the model conversion "3NF to Star Schema". The end result of the transformation results in the Facts and Dimensions to be Views.

  • Recommended Usage - Transitioning from "Physical" category to "Star schema" category.
  • Where to From here - Apply model conversion "Generate Load and Stage tables".

Model Conversion to use in the Star schema category.

Model conversion

Description

Create artificial keys

Transforms business relationships in a Star Schema model by copying the surrogate key attributes into the Fact Tables with an index and an artificial key relationship to the Dimension's surrogate key attribute.

  • Recommended Usage - In the workflow of a "Star schema" category. Safe to re-apply.

Model Conversion for transitioning from Star schema category to Load and Staging category.

Model conversion

Description

Generate Load and Stage tables

Transforms a Star Schema model to generate the Stage and Load entities required for processing data and applying soft business rules.

  • Recommended usage - Transitioning from "Star Schema" category to "Load and Stage" category.
  • Where to from here - Run the Prepare for RED wizard.

This model conversion defines the information on the hash keys for Satellites that is required for WhereScape RED.

ws3d_rvls - Merge and clean up stages

This model conversion merges the temporary Stage entities into their final forms and bringing together the Satellites to their relevant Hubs and Links.

ws3d_rvls - Create loads

This model conversion creates the Load entities from all Stage entities.

ws3d_rvls - Housekeeping

This model conversion tidies up any attribute properties that don't need to be sent to WhereScape RED.

Generate Business Vault Group

Model Conversions for transitioning from Data Vault category to Business Vault category.

Model conversion

Description

ws3d_gbv - Create Satellite View Layer

Generates two layers of views for each Satellite:

  • The current view only returns the latest record from Satellite.
