Schema types

Schema types define how database schemas are organized in AnalyticsCreator and what role each schema plays in the generated data warehouse architecture.

Use this section to understand the available schema types and how they structure staging, historization, transformation, core, and data mart layers.

Available schema types

Staging

Used to store imported source data before further processing.

  • Initial landing layer
  • Holds imported source structures
  • Basis for downstream historization and transformation

Open reference

Persisted staging

Used to store persistent and historized source data for further processing.

  • Persistent source-related layer
  • Supports historization and reprocessing
  • Separates source loading from downstream logic

Open reference

Transformation

Used for generated transformation logic that shapes and combines source data.

  • Transformation-oriented layer
  • Typically contains generated views or logic objects
  • Used between source-related and business-oriented layers

Open reference

Core

Used to store business-oriented structures such as integrated dimensions, facts, or Data Vault-based core models.

  • Central business logic layer
  • Contains integrated warehouse structures
  • Feeds downstream analytical layers

Open reference

Datamart

Used to expose data in a form intended for analytical consumption and reporting.

  • Consumption-oriented layer
  • Typically contains facts and dimensions for reporting
  • Basis for semantic models and BI tools

Open reference

How to choose a schema type

  • Use Staging for imported source data
  • Use Persisted staging when persistent and historized source data is required
  • Use Transformation for intermediate transformation logic
  • Use Core for integrated business-oriented warehouse structures
  • Use Datamart for reporting-ready analytical structures

Key takeaway

Schema types define the structural layers of the generated data warehouse, from source-oriented staging through core integration to reporting-ready data marts.
