Silver Layer (Medallion Architecture)

The Silver Layer is an integral part of the Medallion Architecture, which is a data architecture framework designed to handle and process large-scale data streams efficiently. In the Medallion Architecture, data is organized into three distinct layers: Bronze, Silver, and Gold. Each layer serves a specific purpose, and together they ensure data quality, accessibility, and usability.

The Silver Layer is primarily responsible for creating a clean, enriched and structured dataset from raw data. This layer is a transformative step that includes data cleansing, deduplication, and validation, transforming data extracted from the Bronze Layer into a refined and optimized form that is suitable for more advanced analytics. The Silver Layer typically involves the application of business logic and rules to ensure that the data is accurate and tailored for specific business needs. For a deeper look at how these transformations fit into the full architecture, see how ER/Studio models each medallion layer.

Integration with ER/Studio

ER/Studio can significantly enhance the implementation of the Silver Layer within the Medallion Architecture by providing robust tools for data modeling, data governance, and metadata management. When dealing with the complex task of transforming raw data into structured, validated formats, ER/Studio’s features facilitate clear visual representation and cataloging of data models that power the Silver Layer processes.

• Data Architect: ER/Studio’s Data Architect supports the Silver Layer by helping data architects and engineers design logical and physical models that reflect the intended transformations and business logic at this layer. It ensures that all transformations comply with the set data governance policies and standards.
• Enterprise Data Catalog: The Enterprise Data Catalog offers robust metadata management that considerably assists in documenting the processes and transformations that occur in the Silver Layer. It ensures traceability, version control and lineage tracking, enabling seamless audits and compliance checks.
• Collaboration and Sharing: With ER/Studio Team Server, all stakeholders in the data journey can collaborate effectively, ensuring that the Silver Layer’s business rules and transformations are aligned across the team, reducing errors and improving data accuracy.
