Best Practice to Develop Persistence or DAO Layer

In this video, we will discuss a few best practices that we need to follow while developing the Persistence/DAO layer.

The Data Access Object (DAO) pattern is a structural pattern that allows us to isolate the application/business layer from the persistence layer (usually a relational database, but it could be any other persistence mechanism) using an abstract API.
