As being a newbie we always have a doubt about the new technology and these doubt leads us to failure. I will try to explain you how can you start your Salesforce journey as simple as possible.

First thing that hit in our mind is what is salesforce?
Salesforce is a company that makes cloud-based software designed to help businesses. It provides customer relationship management (CRM) software solution for sales, service, marketing, collaboration, analytics and many more.

Your Business or Organisation might need a way to handle bulk of customer related data. Salesforce allow you to manage these type of requirement easily.
 

If you are fresher and looking for some jobs related to Salesforce Technology you might found out various opening for Salesforce Admin or Salesforce developer.

Salesforce Admin?
 A person who is responsible for handling client or her organisation requirement by using point and click tool provided in Salesforce CRM.

Salesforce Devloper?

Everything is not possible by using point & click tool. Your client might come with such type of requirement which is not possible through direct functionality provided by Salesforce so, in such scenario you might need to code.
