Hello Ponnumani.

There are a few resources you can use.

We have tutorials in our documentation. If you use the link below

http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls

or open the documentation in your instance, you'll see that there are links to tutorials and guides on the side of the page.

You can also select the specific technology you're interested in.  

Additionally, learning.intersystems.com has online courses such as Caché Objectscript Basics that can be of help.
