You can follow this learning learning path from Mendix academy. It helps you to build a similar app with yours. I believe it will help you a lot to have an idea about the concept:

Hi Priyanka, the best way forward is to follow up on Mendix Academy learning paths for intermediate level.
The process you describe is building a complete app. This is not the level somebody can help you with through the forum.
