Data Access Object (DAO)

A Data Access Object (DAO) is a design pattern that acts as an intermediary between an application and its database. It provides a standardized way to retrieve, save, update, or delete data without exposing the complexities of the database itself. Think of it as a dedicated office or interface through which the application communicates with stored data, ensuring consistent and organized data management. This separation makes the application easier to maintain, test, and adapt to changes in the data storage system over time.
