Staging and de-normalized data warehouse tables, in a star schema, with a date table, dimension and fact tables designed for data analysis.
Designing a star schema data warehouse based on the Northwind database and implementing the ETL process using the SSIS tool.
This project documentation was developed as a free project, as a data analyst from the fictional company Sell Boardgames would do in his daily work.
Add a description, image, and links to the star-schema topic page so that developers can more easily learn about it.
