Tasks: Individual units of work, such as executing SQL queries or running scripts.
Containers: Groups of tasks that can be managed and executed together.
Precedence Constraints: Define the order in which tasks are executed based on conditions or outcomes.

Data Flow

Data flow is central to SSIS 950, handling the movement and transformation of data. It involves:

Data Sources: Connections to various data sources like databases, flat files, or web services.
Transformations: Operations that modify data, such as filtering, sorting, or aggregating.
Data Destinations: Where the transformed data is loaded, such as data warehouses or reporting databases.

Event Handlers

Event handlers in SSIS 950 manage events and exceptions that occur during package execution. They allow users to define actions that should be taken in response to specific events, such as:

OnError: Actions to take when an error occurs.
OnWarning: Actions to take when a warning is generated.
OnTaskFailed: Actions to take if a specific task fails.
