Understand the Layering concept
Layering concept
The layering concept in biGENIUS-X is based on the Medallion architecture containing three layer Groups:
The source data are ingested into the Bronze layer, cleaned from the Bronze layer to the Silver layer, and then curated from the Silver layer to the Gold layer.
Then, using the Gold layer data in various reporting tools is possible.
Bronze Layer Group
The Bronze Layer Group has the following characteristics:
- It is the Landing stage
- It has the same structure as the Source system
- It is immutable (read-only)
- It can be historized based on delivery
Use cases:
- Historic reloads
- Debugging
- Testing
It includes the following Layers:
- Stage
- Data Store
Silver Layer Group
The Silver Layer Group has the following characteristics:
- It is cleansed and filtered
- It is historized (SCD2)
- It is modeled along subject areas
Use cases:
- Used by operational analytical teams
It includes the following Layers:
- Data Vault modeling:
- Raw Vault
- Business Vault
- Dimensional modeling:
- Dimensional
- Relational modeling:
- Core
Gold Layer Group
The Gold Layer Group has the following characteristics:
- It is highly governed
- It is well-structured & documented
- Can be historized based on the use case
- Complex business rules are applied
Use cases:
- Used for reporting and analysis
- To provide ready-to-use reporting
It includes the following Layers:
- Data Mart
