What is SSIS container? Containers are objects that help SSIS provide structure to one or more tasks. They can help you loop through a set of tasks until a criterion has been met or group a set of tasks logically. Containers can also be nested, containing other containers. They are set in the Control Flow tab in the Package Designer.
What is SSIS used for? SSIS is a platform for data integration and workflow applications. It features a data warehousing tool used for data extraction, transformation, and loading (ETL). The tool may also be used to automate maintenance of SQL Server databases and updates to multidimensional cube data.
What is the use of for loop container in SSIS? The For Loop container defines a repeating control flow in a package. The loop implementation is similar to the For looping structure in programming languages. In each repeat of the loop, the For Loop container evaluates an expression and repeats its workflow until the expression evaluates to False.
What is a control flow task in SSIS? Creating a control flow includes the following tasks: Adding containers that implement repeating workflows in a package or divide a control flow into subsets. Adding tasks that support data flow, prepare data, perform workflow and business intelligence functions, and implement script.

What are enumerators in SSIS?
The file enumerator loops through a collection of files within a folder and makes it possible to execute for example a Data Flow Task for each of the files without manually changing the connection string.

What is the difference between control flow and data flow in SSIS?
The major difference between control flow and data flow in SSIS is that Control Flow can execute only one task at a time in a linear fashion. On the other hand, Data Flow can perform multiple transformations at the same time.

SSIS Expression Task: creates and evaluates expressions that set variable values at runtime. Variables: can be evaluated as an expression. Task properties: several properties can be set as expression so they can change at runtime More information at Use Property Expressions in Packages.
Can I use Python in SSIS?
If you are using a lot of SSIS packages for complex ETL, this conversion process can be quite lengthy.
If you are already running Python 2 in your organization, there is no need to upgrade to Python 3 just to do ETL.
Both Python and T-SQL will continue to work just fine in newer versions of SQL Server.
