Hi @Shakti337,
Welcome to Alteryx and welcome to community!
I think the best place to start is the training section of our website.
I would recommend going through the getting started videos below
http://www.alteryx.com/getting-started-training
If you have the time, I also highly recommend going through the self paced training exercises that we have posted
http://www.alteryx.com/self-paced-training
Completing the beginner and intermediate sections should give you a great overview on the commonly used tools within Alteryx.
If you get stuck along the way, feel free to ask us a question here on community in the discussions section.
Thanks!
