SQL Server Integration Services(SSIS)

· SSIS makes it easy to create robust and complex solutions for extracting, Transforming and Loading the data.

· These will help you to design, create, deploy and manage packages that address everyday business requirements.

· SSIS can be used for data migration as well as data integration purpose.

· Other ETL tools are

Informatica, DataStage, abinito and data integrator.

SSIS Dev roles:

· Developing packages

· Error handling

· Debugging of packages

· Optimizing packages

· Using Scripting SSIS packages.

SSIS Administrator Roles:

· Installation

· Configuration

· Deployment

· Security

· Executing the packages

Manually

Scheduling

· Monitoring and trouble shooting in SSIS.

SSIS Architecture:

It means that four components.

1. SSIS Object model

2. SSIS Service

3. SSIS Runtime engine and

4. Dataflow engine.

1. Develop the SSIS packages by consuming the ssis object model.

2. SSIS service will manage the deployed packages.

3. SSIS runtime engine will execute the different tasks in the package.

4. Dataflow engine will executes the dataflow tasks in the package.

Sections in SSIS Designer:

Control Flow:

Work flow of task execution / order of tasks execution.

Controlling the flow of SSIS package execution.

Data Flow: ETL

It contains extracting the data from one more sources with the help of source adapters, performing transformations and loading the data into one more destinations with the help of destination adapters.

Event Handlers:

It allows you to implement error handling and debugging of control flow tasks in SSIS packages.

Package Explorer:

It allows you to browse the package contents. Package contains tasks, precedence constraints, log providers, variables, event handlers and connection managers.

Parameters:

Parameters are the replacement for configurations that are in the current version of SSIS. It allows you to assign values to properties within packages at the time of package execution.
