To keep things organized, folders are created to store the C# files that represent models and data handlers. Models are C# classes that define entity structure. Each class usually maps directly to a database table. Some types of databases (called no-SQL) do not have tables per se. That is why we refer to the model class as an entity and not specifically a table. All the models will go in the Models folder.

The models are simple C# classes with the name representing an entity. Think of this as a spreadsheet with tables that have columns with header names and rows with data. Each sheet is an entity. Each column in the sheet has a name. The property names in the model class are the same as the spreadsheet column names. They represent the schema. One difference is that each property must have a data type. That is a basic premise of the strongly typed C# approach. Each property has a getter and setter which means it can be written to and read from. An example model class would look like this:

public class Student
{
   public string ID { get; set; }
   public string Name { get; set; }
}
