Loading Data

After a SQL Server 2005 Integration Services (SSIS) package contains a Data Flow task, you can begin to create the package data flow. Integration Services includes three types of data flow components: sources, transformations, and destinations.

The following diagram shows a simple data flow with a source, two transformations, and a destination.

Data flow

You use the destinations to load data into files and databases and provide data to other processes. For example, the DataReader destination can provide data for a Reporting Services report. A data flow can include multiple destinations that load data into different data stores. For more information, see Integration Services Destinations.

You can also write custom destinations. For more information, see Developing a Custom Data Flow Component and Developing Specific Types of Data Flow Components.

After you add the source to the data flow designer and configure the source, you can add the destination to the data flow designer. Before you finish configuring the destination, you must connect the destination to the data flow by connecting the output of another transformation or source in the data flow to the input of the destination. The connector between two data flow components is called a path. For more information about connecting components and working with paths, see Connecting Components.
