SSIS functional units are Packages…

  • …then within Packages:
  • Control Flow
  • Data Flow

SSIS

ssis packages

Connection managers

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

SSIS Packages

connection managers

Connection Managers

Components which refer to a data source or destination

checkpoints

Key Properties at Package Level:

  • CheckpointFileName
  • CheckpointUsage
  • SaveCheckpoints
  • FailPackageOnFailure = True for all restart points

Checkpoints

event handlers

Event Handlers

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