Help with Database Design for a CRM

I am creating a CRM for a call-center and I want to store the input field data in a database. My problem is that I am quite new to this ordeal and have little - to no idea how to structure my database. Should I create multiple tables for each part of the form and submit the data there or should everything be submitted to one large table? Note 1: the form has around 80 fields with the data I need. Note 2: I also have another form with approximately 50 fields and plan to add another form which will be much small with app. 15 fields. I appreciate any help and thank you for your time in advance!
