Data Centric World

The Silver Layer is an essential component of the Medallion data warehouse architecture, as it sits between the source systems and the analytical layer of the warehouse. The primary function of the Silver Layer is to prepare and cleanse data before it is loaded into the analytical layer. This is done to ensure data accuracy and consistency, making it suitable for analysis and decision-making. The Silver Layer is composed of three critical components: data integration , data quality , and data transformation . Data Integration involves collecting data from various sources and integrating it into a single dataset. This process involves extracting data from source systems, transforming it into a common format, and loading it into the Silver Layer. The goal of this component is to ensure that all data is in a consistent format, making it easier to analyze and report on. Data Quality is essential in any data warehouse. Poor data quality can lead to inaccurate reporting, flawed analyses, ...
