A Data Warehouse Developer is primarily responsible for designing, building, and maintaining the data infrastructure that supports the organization's data needs. They analyze and interpret business requirements to develop robust solutions that aggregate data from different sources into a centralized repository. This involves creating and managing ETL (Extract, Transform, Load) processes to ensure data integrity, consistency, and accuracy. These professionals also maintain and optimize data models, write complex SQL queries, and ensure that data is stored in a way that facilitates fast and accurate retrieval for business analysis. Moreover, they rigorously test and troubleshoot systems to identify and fix any discrepancies or performance issues, always seeking to improve the efficiency and scalability of the data warehouse.
