Unit 14: SQL Server Integration Services




               SSIS creates packages which are composed of tasks that can move data from source to  Notes
               destination, and if necessary transform it.

               Within SSIS package the workflow can be defined, the SSIS runtime engine ensures the
               tasks inside the package are executed according to the workflow.

          14.7 Keywords

          Connection Manager: A connection manager is a logical representation of a connection.

          Connections: A connection includes the information necessary to connect to a particular data
          source.
          Containers: Containers group a variety of package components (including other containers),
          affect their scope, sequence of execution and mutual interaction.
          Event Handlers: A workflow can be designed for a number of events in the different scopes
          where they might occur.

          Package: A package is a collection of tasks which are executed in an orderly fashion by SSIS
          runtime engine.
          Precedence Constraints: Tasks are linked by precedence constraints. The precedence constraint
          preceding a particular task must be met before that task executes.
          Tasks: A task is an atomic work unit that performs some action.
          Variables: Tasks may reference variables to store results, make decisions, or affect their
          configuration.
