DAL class structure for storing and organizing SQL using Dapper?

I’m creating a web application with Asp.Net Core MVC, and I’ve replaced Entity Framework with a custom data store. I’ve decided to use Dapper, but have never used it prior to this project. So I’m learning what I need to as I go. One of the examples I referenced to help replace EF with my own custom storage provider used a backing class for each table to organize and store routine queries for that particular table.
