2. WHAT IS SSIS?
Integration Services is a platform for building high
performance data integration and workflow solutions,
including extraction, transformation, and loading (ETL)
operations for data warehousing.
Transfer and transform data
SSIS contains a data-flow engine to transfer and transform
data to and from varied data sources
Tools and wizards
SSIS contains graphical tools and wizards for creating an
extraction, transform, and loading system
New version of DTS (Data Transformation Services in SQL
Server 2000)
3. TYPICAL USE OF INTEGRATION
SERVICES
Merging Data from Heterogeneous Data Stores
Populating Data Warehouses and Data Marts
Cleaning and Standardizing Data
Building Business Intelligence into a Data
Transformation Process
Automating Administrative Functions and Data
Loading
6. SSIS ARCHITECTURE
Integration Services has a completely new
architecture that separates data movement
and transformation from Package control flow
and management
Packages are the units of work that you
execute
Tasks do the work in packages
Containers are objects that provide structure
to packages
7. -The run-time engine implements
the control flow and package
management infrastructure
-The data flow engine
is a specialized, high performance
engine that is exclusively
dedicated to extracting,
transforming, and loading data.

How to Deploy Packages
11. DATA SOURCES AND DATA SOURCE
VIEWS
Data sources
A data source is a connection reference that you create
outside a package.
A real-time reference to a data store connection, which
includes all tables and views in the data store.
Data source views
Provide a subset of data from a data source
You can extend a data source view by adding calculated
columns that are populated by custom expressions,
adding new relationships between tables, replacing
tables in the data source view with queries, and adding
related tables.
12. CONNECTION MANAGER
A connection manager is a logical representation
of a connection
Different types of connection managers enable
packages
to connect to a variety
of data sources and
servers
13. PACKAGE CONTROL FLOW
Tasks
Tasks do the work in packages. The most
important task is the data flow task
Precedence constraints
Precedence constraints join tasks together
Containers
Containers allow you to group together, or loop
through, the tasks
14. DEPLOY PACKAGE
Define package configurations
Allow you to update the values of properties at run time
Build the project
Configure the deployment utility
Build the project
Deploy the build
Copy the build folder to the new system
Run the manifest
15. SSIS EXECUTION METHODS
Visual Studio / BIDS
Debugging environment
Command Line – (dtexec)
Execute Package Utility (dtexecui)
SQL Agent Sub System
Object Model
16. SSIS DESIGNER
Available in Business Intelligence Development
Studio as part of an Integration Services project.
Perform the following tasks:
Constructing the control flow in a package.
Constructing the data flows in a package.
Adding event handlers to the package and package objects.
Viewing the package content.
At run time, viewing the execution progress of the package.
17. PACKAGES DEBUGGING
Control flow
Breakpoints
Progress reporting
Debug window
Data flow
Data viewer
Row counts
Progress reporting
18. SECURITY
Packages signed with certificates
Data encryption before saving the package
Packages protected using passwords
Packages controlled with database-level
roles, by default:
Administrator
User
Operator
19. COMPATIBILITY
Possibility to run DTS and SSIS packages
Use ‘Execute DTS 2000 Package Task’ for running
DTS packages from Integration Services Packages
Use ‘Package Migration Wizard’ for migrating
packages with SQLServer 2000 DTS format
20. MIGRATION LIMITATIONS
Doesn’t migrate ActiveX Script code with that
accesses the DTS object model via parent
property of the Global Variables
Doesn’t migrate Analysis Services tasks
Doesn’t migrate Complex Data transformation
tasks
Doesn’t migrate customs tasks
Doesn’t migrate dynamic properties
Doesn’t migrate parallel data pumps
Doesn’t migrate ActiveX Script attached to
package steps
Doesn’t migrate transaction settings
Data is typically stored in many different data storage systems, and extracting data from all sources and merging the data into a single, consistent dataset is challenging.
The data in data warehouses and data marts is usually updated frequently, and the data loads are typically very large. Integration Services includes a task that bulk loads data directly from a flat file into SQL Server tables and views, and a destination component that bulk loads data into a SQL Server database as the last step in a data transformation process.
Whether data is loaded into an online transaction processing (OLTP) or online analytic processing (OLAP) database, an Excel spreadsheet, or a file, it needs to be cleaned and standardized before it is loaded.
The data may need to be summarized, converted, and distributed based on data values. The process may even need to reject data, based on an assessment of column values.
Administrators frequently want to automate administrative functions such as backing up and restoring databases, copying SQL Server databases and the objects they contain, copying SQL Server objects, and loading data. Integration Services packages can perform these functions.
-Integration and warehousing require separate, staged, operations.
-Preparation of data requires different, often incompatible, tools.
-Reporting and escalation is a slow process, delaying smart responses.
-Heavy data volumes make this scenario increasingly unworkable.
-Integration and warehousing are a seamless, manageable, operation.
-Source, prepare and load data in a single, auditable process.
Integration Services supports both native and managed code.
The Integration Services service, monitors running Integration Services packages and manages the storage of packages.
The SQL Server Import and Export Wizard provides the simplest method of constructing basic packages and copying data between data sources.
The Package Installation Wizard guides you through the process of deploying packages and updating package configurations.
The Package Configuration Wizard guides you though the steps to create the configurations that update the values of properties of packages and package objects at run time.
The Package Migration Wizard guides you though the steps to migrate SQL Server 2000 DTS packages to SQL Server 2005.
