What is the difference between Control Flow and Data Flow in SSIS?

In SSIS, Control Flow and Data Flow are two important components that serve different purposes:

Control Flow:

The Control Flow is responsible for defining the workflow and order of tasks in an SSIS package. It consists of tasks and containers that control the flow of execution, such as Execute SQL Task, File System Task, For Loop Container, etc. Control Flow determines the sequence in which tasks are executed and allows conditional branching based on expressions or constraints.

Data Flow:

The Data Flow is used for extracting, transforming, and loading data between sources and destinations. It includes components like Source, Transformation, and Destination that facilitate data movement and manipulation. Data Flow tasks handle the actual movement and transformation of data within an SSIS package.

Overall, Control Flow focuses on the control and orchestration of tasks, while Data Flow handles the movement and transformation of data within the SSIS package.
