In this hands-on lab scenario, your organization, Awesome Company, is reducing its on-site footprint and moving as many databases as possible to the cloud. As part of this effort, you have already migrated one of your primary sales databases, `acweb`, to Azure SQL Database. As the utilization of this database increases, you need to implement database maintenance tasks to keep it running in top condition. Performing the actions of this lab will help you become familiar with manually executing database maintenance tasks.
