  DAO stands for Data Access Object. It’s a design pattern in which a data access object ( DAO ) is an object that provides an abstract interface to some type of database or other persistence mechanisms. By mapping application calls to the persistence layer, DAOs provide some specific data operations without exposing details of the database. This isolation supports the Single responsibility principle. It separates what data accesses the application needs, in terms of domain-specific objects and data types (the public interface of the DAO), and how these needs can be satisfied with a specific DBMS, database schema, etc. (the implementation of the DAO). While developing an enterprise application, one of the most important aspects is to deal with the DB like connection management, transaction management etc. Initialization of data access object, resource management and transaction management and exception handling are the main parts of persistence framework.
