SQL Server Integration Services
SQL Server Integration Services (SSIS) is a Microsoft platform for building enterprise-level data integration and workflow solutions. It provides tools for extracting, transforming, and loading (ETL) data from various sources into destinations like databases, data warehouses, or files. SSIS includes a graphical design environment for creating packages with control flows, data flows, and event handlers.
Developers should learn SSIS when working in Microsoft-centric data environments, especially for ETL processes in SQL Server ecosystems, data migration projects, or business intelligence workflows. It's particularly useful for automating complex data transformations, handling large-scale data loads, and integrating with other Microsoft tools like SQL Server, Azure Data Factory, or Power BI.
