Difference between Control flow and data flow

Control Flow

Control Flow is part of SQL Server Integration Services Package where you handle the flow of operations or Tasks. Let's say you are reading a text file by using Data Flow task from a folder. If Data Flow Task completes successfully then you want to Run File System Task to move the file from Source Folder to Archive Folder. If Data Flow Task failed then you want to sen

d email to your users by using Send Mail Task. The Precedence Constraints are used to control the execution flow.

Data Flow

Data Flow is the part of SQL Server Integration Services Package, where data is extracted by using Data Flow Sources (OLE DB Source, Raw File Source, Flat File Source, Excel Source etc.). After extracting data Flow Transformations such as Data Conversion, Derived Column, Lookup, Multicast, Merge etc are used to implement different business logic and finally written to Data Flow Destinations (OLE DB Destination, Flat File Destination, Excel Destination, Data Reader Destination ADO NET Destination etc.)
