What Is SQL Server Integration Services
SQL Server Integration Services (SSIS) is a platform for building high-performance data integration and workflow solutions. It is a component of the Microsoft SQL Server database software that can be used to perform a wide range of data integration and migration tasks, such as extracting data from various sources, transforming and cleaning it, and then loading it into a destination database or data warehouse. SSIS also supports the creation of custom tasks and transformations, as well as the integration of data from a variety of sources, including databases, flat files, and Web services.
SQL Server Integration Services (SSIS) can import data from a variety of sources, including:
Relational databases: SSIS can import data from various relational databases, such as SQL Server, Oracle, MySQL, and others.
Flat files: SSIS can import data from flat files, such as CSV, Excel, and text files.
OLE DB and ADO.NET data sources: SSIS can import data from OLE DB and ADO.NET data sources, such as Access, Excel, and other data sources that support the OLE DB or ADO.NET interfaces.
XML data: SSIS can import data from XML files or Web services.
Web services: SSIS can import data from Web services through the use of Web Service Task.
Data from other sources: SSIS can import data from other sources using the Script Task or the Execute Process Task.
It's important to note that SSIS can also import data from multiple sources at the same time and also supports real-time data integration using the CDC (Change Data Capture) feature.
