SQL Server Integration Services (SSIS) is widely used whenever data from outside sources is loaded into a SQL Server database. Extract, Transform, and Load (ETL) processes feeding data marts and business intelligence systems are two common scenarios in which SSIS is used, and it's often the case that SSIS's built-in feature set can be enhanced to make loads run faster, and to otherwise process data so as to save time and provide business benefit. This book shows how to create such enhancements by way of custom SSIS tasks built using a free toolset provided by Microsoft in the form of Visual Studio Community Edition and the Visual Basic language.
