SSIS SSIS functional units are Packages…

…then within Packages:

Control Flow

Data Flow

SSIS Packages

• Connection managers • Checkpoints• Event Handlers • Configurations• Variables & Expressions• Logging

Connection Managers

Components which refer to a data source or destination

CheckpointsKey Properties at Package Level:

• CheckpointFileName• CheckpointUsage• SaveCheckpoints

FailPackageOnFailure = True for all restart points

Event Handlers

As packages execute, a series of events occur, e.g: • Validation Completing• Errors• Variable values changing

Configurations

Configurations are External Sources

of

Package Execution Settings

Variables & Expressions

Variables provide changeable values to be used by packages

SSIS has its own expression language

Logging

Logging Providers record execution details
