I kinda stuck how to implement the UOF without using any framework every example I found on the internet uses EF to handle UOF and Repositories work, what if in the future I wanted to use MongoDB (which don't support transactions over different documents) or a remote HTTP API provider?

thank you for your clear explanation, I think you should post this as an answer so I can mark it.

thank you for your reply, I thought that too only confused about where to store those types (should it be an int that passed to each employee constrcutor or an enum in my library or just a fixed readonly int in each class)?

thank you for your replay and the factory pattern is very good but if this is Ok I have the following question:
how should this be stored in the database
if each emp concrete class has its own table how to apply a get all employees method?
should I have a BaseEmp table to store the names and each emp concrete class have its details in another table.
