I am currently building a c# application that gets JSON data then it calculates something then stores the results in a database, what is the proper way to design the application.

This is how it's now

• I have a static class that gets and parses the JSON then stores it in an object and all objects are then stored in an object list.
• I then have a static class that loops through the object list and calculates the results base on each objects values.
• I then have a static class that stores the results in the database.
• And I have the main class that calls everything.

I think that I am overusing the static classes and could replace one or a couple with simple method (in the main class) instead of having a separate static class for it, am I?
