Using this setup can save a lot of money. It also helps manage data better and faster.
What Is Medallion Architecture?
Medallion Architecture helps you organize your data in a clear way. You use this design to make storing and finding data easier. Many big data systems use Medallion Architecture because it works well with lots of data. The word "medallion" means you improve data in steps, like making metals better.
Medallion Architecture puts your data into three layers: Bronze, Silver, and Gold. Each layer is a new step in processing. Your data gets more useful and trustworthy as it moves through each layer.
Layered Data Model
A layered data model gives your data more order and makes things clearer. You can clean and change your data one step at a time. It is easy to see what changes happen, which helps with rules and laws. The layers also help you check your data and see how it moves.
Objective | Description |
|---|---|
Holistic view of enterprise data | |
You set up data for different users and needs. | |
Data governance and compliance | You keep your data correct and follow the rules. |
Incremental improvement | You make your data system better as your business grows. |
Bronze, Silver, and Gold Layers
Each layer in Medallion Architecture does something special:
Bronze Layer: You keep raw data here. This layer can hold many types, like JSON or CSV. It is the first place for all data changes.
Silver Layer: You clean and organize your data here. You set rules, check for mistakes, and remove copies. You also add more details by joining data.
Gold Layer: You get business-ready data here. This layer has summaries and totals. It is made for fast searches and uses easy names. You also set who can see what.
Layer | Contribution to Data Quality and Business Value | |
|---|---|---|
Bronze | Raw, unprocessed data; schema-on-read; high volume | Gives a base for more changes and study |
Silver | Cleaned, structured, deduplicated data; transformations | Adds value by making data better and joining events |
Gold | Aggregated, business-ready data; optimized for analytics |
You can trust your data more as it moves through the layers. Each step makes your data better and ready for business.
Building a Robust Data Foundation
Data Quality and Trust
You want your data to be right and easy to trust. Medallion Architecture helps by using clear steps and checks in each layer. Bronze, Silver, and Gold layers add order and make data better. You can watch how your data changes and know when it is ready for work.
