Common Deployment Issues
• Data source connection has wrong server/database name.
• The impersonation is not set properly.

Modeling Best PracticesUse views for data source when possibleRename objects sooner vs. laterLimit data when modelingPay attention to data typesReduce cardinality: Split DateTime columnsUse partitioning for large tables
