DAO Interface | DAO Tutorial for Beginners

In this DAO tutorial for Beginners we will learn how to create a Data Access Object Interface. The DAO Interface defines the standard operations to be performed on model objects. It is an abstraction of the class that will hold the concrete implementation of our persistence logic.

Eclipse Project code is available on GitHub

hey, thanks for the video. Do we really need the Update and Insert method when we already have the save() method?

Can we write test for Crud operations without object(DTO, DAO) in our JDBC implementation, like methods (Delete by id, insert...etc) ?

Hi Dave, what happened to the 'T' class between video #3 and #4? Having a few issues making your code run as I've followed along in this series, and I've traced it back to some miscommunication between videos 3-4.

So in this example DAO wouldn't work for reading employees from a CSV or Excel file nor a Monge / no-SQL database. Seems really fragile and overly coupled to a single paradigm and expectation to me. Isn't that what DAO was supposed to prevent?
