The DAO pattern provides the connection between the business logic tier and the resource (usually a database) tier. The Data Access Object represents a general interface to the resources layer: It handles all calls to it. JDBC is the most commonly used example of this. Almost all J2EE Applications that access the database have a direct or indirect implementation of the DAO Pattern.
This pattern is an object that encapsulates a set of behaviors for accessing databases, files, and other resources. This way you have only one API to deal with rather than a different one for every type of resource.
This is not a pattern for a resource itself. Frankly speaking, this isn't a way to build a database or file manager.
This is like using an ATM machine. The same interface will fetch the information requested from the back end, even though the bank changed database products the previous week.

What is the difference between ado rdo and dao?
ADO is active x data object. It is used to access database with the help of data controls and objects as well. it is an extended form of RDO and DAO. RDO is remote data object which is used to access server site data. data in this case reside on the sql server. and we use sql queries to access data. in this we write a sql command and then squ server processes it and gives back the result. DAO is data access object. it is used to access data with the help of program and some data controls. it provides an extention to data controls and data bound controls. DAO helps in accessing data with various conditions or quries.
What are the key differences between C struct and class, and how do they impact the design and implementation of object-oriented programs in C?
In C, the key differences between struct and class are that struct members are public by default, while class members are private by default. This impacts the design and implementation of object-oriented programs as structs are typically used for simple data structures with public access, while classes are used for more complex objects with private access and encapsulation. This difference in access control affects how data is managed and accessed within the program, influencing the overall design and organization of the code.
