Developing a Custom Data Flow Component

The data flow task consists of components that connect to a variety of data sources and then transform and route that data at high speed. Microsoft SQL Server Integration Services provides an extensible object model that lets developers create custom sources, transformations, and destinations that you can use in Business Intelligence Development Studio and in deployed packages. This section contains topics that will guide you in developing custom data flow components.
