Welcome to Interview Questions for SSIS, In today’s blog we’ll be talking about SSIS technology as it applies in various IT roles SQL Server Integration Services allows for extracting, transforming, and loading of data between sources.

SSIS technology offers many uses in IT, from data warehousing and business intelligence to integration of various sources like databases, flat files, and web services into an easily usable format that can then be easily visualized or analyzed.

SSIS not only supports data extraction but can also transform it during its loading into a data warehouse or mart. This enables you to transform, clean, normalize, and ensure it remains accurate over time.

SSIS provides various tools and components to facilitate data integration, connecting disparate sources. This includes data flow tasks used for extracting, transforming, and loading into warehouses/marts.

SSIS technology is an efficient, versatile solution designed for multiple IT roles. Be it data warehousing, business intelligence, or data integration.
