**SSIS-- GUI based ETL tool

* works on client server architecture i.e
-- ssis applications which are used for integrating are developed on client machine
    and deployed on server machine , so that every one uses those.

* Applications are developed by creating packages( collection of all items)

* Packages can be designed in two ways

1)SSIS wizard( Import and export data tool):
 
*only simple packages are developed by import and export data tool

*go to "import and export data tool" or run--dtswizard

 Executing packages:

1) Open execute package utility or run--dtsexecui

2) By using command line utility--C:\>dtexec/F<path>

Example 1:

load data from text file into table.

choose create table option--- means package runs first time w/o error, but on second execution on wards it raise error because already table exists in database
