Extract Transformation & Load Extract data from one or more sources Transform source data

Standardize, Cleanse, Convert, Conform/Fix Load data into one or more destinations

SSIS Package

Control Flows Data Flows Connection Managers Event Handlers Logging Providers

SSIS Package Lifecycle

Develop Build in SQL Server Import and Export Wizard Build in Business Intelligence Development Studio

Store File System (as .dtsx file) SQL Server (in MSDB database)

Execute DTExec or DTExecUI utility application Business Intelligence Development Studio (BIDS) SQL Server Management Studio (SSMS)

Tools for Building SSIS Packages

SQL Server Import and Export Wizard Accessed from DTSWizard.exe, SSMS, BIDS

Business Intelligence Development Studio

Control Flow Designer Control Flows are the program logic of an SSIS

package Drag and Drop to implement tasks Control Flow Tasks include:

File System, FTP, Execute Process, Execute SQL For Loop, ForEach Loop Containers Sequence Container Send Mail Task Script Task

Data Flow Designer Provides access to core ETL functions 3 main categories of Data Flow components

Data Flow Sources Data Flow Transformations Data Flow Destinations

Common Source/Destinations Include: OLEDB (Ex: - SQL Server) Flat Files (Ex: - binary file, .csv) Excel, XML

Event Handler Designer

Events exposed by package executables Loops, Sequence containers, for example

Designate handlers for runtime events Can perform setup, teardown actions,

notifications on completion

Package Designer

Provides hierarchical view of package contents View

Connections Executables Tasks Event Handlers Log Providers Precedence Constraints Variables

Connection Managers

Represents connection to data sources and destinations

Created, stored per-package Can be shared by multiple package components
