It's part of Microsoft's SQL Server suite but can also be used with other data sources. However, the cost of SQL Server and, by extension, SSIS can be prohibitive for individuals or small businesses looking to leverage its capabilities. ssis971 free

Troubleshooting (common issues)
- Provider not found: install required OLE DB/ODBC drivers matching package bitness (32- vs 64-bit).
- Package failed on SQL Agent: check job step execution options (Run as 32-bit or 64-bit).
- Permissions errors: verify service account access to file shares and databases.
- Variable/config mismatch: confirm parameter names and paths when using /SET or configurations.
Logging & Monitoring
- Enable package-level logging: choose a provider (Text, SQL, Windows Event Log).
- Configure events to capture: OnError, OnWarning, OnInformation, OnPreScript, OnPostExecute.
- Aggregate logs to a central SQL table for queries and alerting.
