The main difference between data warehousing and data mining is that data warehousing is the process of compiling and organizing data into one common database, whereas data mining is the process of extracting meaningful data from that database.

A data warehouse stores historical data about your business so that you can analyze and extract insights from it. A clinical data repository consolidates data from various clinical sources, such as an emr, to provide a clinical view of patients. Data repositories enterprise data warehouse.
