Data Access Object. It's a common design pattern.

DAO stands for Data Access Object, which contains all data base related methods.

For example you want get the list of employees from Data base.

class EmpDAO{
public ArrayList getEmployees(){
//Query to get all employees
//Keep the data in ValueObjects
//Add the valueobjects to ArrayList
return theArrayList
}

}

This design pattern helps to separates the database related code and presentation/application code.


Thnx,
sam
