SQL Server to Text File Using SSIS

Dear reader, today we will discuss SQL Server Integration Services (SSIS), a powerful feature of Microsoft SQL Server. SSIS is an upgrade of Data Transformation Services (DTS), which is a feature of the previous version of SQL Server. SSIS packages can be created in Business Intelligence Development Studio.

Use of SSIS

The primary use for SSIS is for data warehousing since the product features a fast and flexible tool for data Extraction, Transformation and Loading (ETL). The tool may also be used to automate the maintenance of SQL Server databases, update the data warehouse and perform other functions.

Step1: Open the business intelligence development studio.
