Data Warehousing Specialists in Analytics
Overview
Data Warehousing Specialists in Analytics design and build large databases that store a company’s most important information, such as sales numbers, customer data, and app activity. They model data structures, write SQL and other code to move and transform data from many systems into one organized “source of truth,” and create testing plans to make sure the data is accurate and fast to use. They also set standards, document how everything works with diagrams and metadata, and help analysts, data scientists, and business leaders troubleshoot problems so they can trust the numbers behind major decisions.
