Data Warehousing Questions
Data loading in data warehousing refers to the process of extracting data from various sources, transforming it into a consistent format, and loading it into a data warehouse. This involves extracting data from operational systems, such as databases or applications, and transforming it to meet the requirements of the data warehouse schema. The transformed data is then loaded into the data warehouse, where it can be accessed and analyzed for reporting and decision-making purposes. Data loading is a crucial step in data warehousing as it ensures that the data in the warehouse is accurate, consistent, and up-to-date.
