How to fill out data warehouse design:
01
Understand the business requirements: Before starting the design process, it is essential to have a clear understanding of the business goals and objectives that the data warehouse is expected to support. This includes identifying the required data sources, types of data to be stored, and potential use cases.

Define data warehouse structure: The next step is to define the structure of the data warehouse.

Extract, transform, and load (ETL) processes: In order to populate the data warehouse, you need to design efficient ETL processes. This includes extracting data from various sources, transforming it to match the data warehouse schema, and loading it into the warehouse tables. Use appropriate tools and techniques for data extraction, cleansing, and integration.
04
Implement data security measures: As data warehousing involves storing sensitive business information, it is crucial to implement proper data security measures. This includes defining access controls, ensuring data encryption, and maintaining regular backups. Compliance with relevant data privacy regulations should also be considered.
