6. Deploy and integrate: Deploy the data warehouse and integrate it with other existing systems or applications. This may involve setting up connectivity, establishing data feeds, or implementing data synchronization processes.
7. Test and validate: Conduct rigorous testing of the data warehouse to ensure that it meets the intended objectives and functions correctly. Validate the data accuracy, performance, and security measures.
8. Monitor and maintain: Continuously monitor the data warehouse to track its performance, identify potential issues, and make necessary adjustments. Regular maintenance activities such as data backups, system updates, and user support should also be carried out.
