What is a Data Warehousing Specialist?
A Data Warehousing Specialist is a professional who is responsible for designing, developing, and maintaining data warehouses, which are centralized repositories of integrated data from one or more disparate sources. These specialists play a crucial role in ensuring that data is stored, managed, and retrieved efficiently for various analytical and reporting purposes.
