- Automates routine tasks like database backups, index rebuilding, statistics updates, etc.
- Reduces manual intervention, ensuring timely execution of critical tasks.
2. Job Execution & Monitoring
- Allows running T-SQL scripts, SSIS packages, PowerShell scripts, or executable files on a schedule.

- Automates ETL (Extract, Transform, Load) workflows in data warehousing.
- Helps with data migration and transformation tasks.
7. Multi-Step Jobs & Dependency Handling
- Supports multi-step jobs, where one step's success or failure can determine the next action.
